9 Cool Facts About Manatees

Manatees, with their large and lumbering nature, exhibit qualities of cuteness, cuddliness, and adorableness, while leading fascinating lives. These creatures are uniquely recognized for their whiskered faces, paddle-shaped tails, and broad backs. Manatees, warm-blooded (endothermic) mammals, inhabit coastal areas and rivers, giving birth to live offspring and carefully nurturing their young. In Crystal River, Florida, the sea cows gravitate towards the warm waters of Kings Bay and Three Sisters Springs as temperatures decrease. When winter arrives, they seek refuge in the warm water springs and subsequently migrate to distant locations during summer. 

So what are some fun facts about manatees?

1. Three distinctive species.

Three species of manatees exist: the Amazonian Manatee, West Indian Manatee, and West African Manatee. All three have a relation to the dugong and are vulnerable, facing the risk of extinction. Boat collisions, habitat destruction, toxic red tides, and hunting pose threats to their population.

2. Manatees belong to the Order Sirenia.

Animals in the Order Sirenia are known as sirenians, encompassing manatees, dugongs, and the extinct Steller’s sea cow. They possess a characteristic broad body, flat tail, and two forelimbs. Coastal ocean waters of the Indian Ocean and Western Pacific constitute their primary habitat. The most noticeable distinction between the living members of the Order Sirenia—dugongs and manatees. Dugongs feature a forked tail, whereas manatees display a round tail. Elephants are the closest living relatives of sirenians—manatees evolved from the same land animals as elephants more than 50 million years ago. Fossil records depict a considerably more diverse array of sirenians than what currently exists. Dugongs and manatees coexisted in various habitats throughout their range.

3. Closest living relatives.

Mammals like walruses and seals closely resemble manatees in shape. However, manatees are not related to these animals; instead, they share a close relationship with land animals such as hyraxes and elephants. Manatees possess thick skin and 3-4 toenails, traits they share with elephants. Additionally, manatees exhibit a shrunken snout, which represents a reduced version of the elephant’s trunk. Similarly, manatees employ their prehensible lips to grasp and pull food into their mouths, much like elephants use their trunks. Unlike most animals with pointed hearts, both elephants and manatees have hearts with a rounded bottom.

4. They are the mermaids seen by explorers.

Sailors at sea who spotted manatees gave rise to the myth of mermaids. However, contemporary understanding deems such sightings as mirage-like hallucinations caused by sleep deprivation, dehydration, or malnutrition on the part of the sailors. Christopher Columbus and other early explorers asserted that they had observed female figures swimming in the ocean, labeling them as mermaids. Today, the exact description they provided for these supposed mermaids aligns most accurately with manatees. However, there are only slight and explainable variations. Manatees have the scientific name Sirenia, derived from Greek sirens—dangerous sea nymphs who enticed sailors with their song, luring them and their vessels toward rocky shores. “Sirenia” is also an alternate term for mermaids. Current understanding confirms that these encounters were, in fact, with manatees.

5. Reason they are called sea cows.

The name “sea cows” is attributed to manatees due to their inclination towards grazing. They also possess a stout, cow-like appearance. Manatees inhabit shallow coastal areas and rivers, where they consume sea grasses, mangrove leaves, and algae. They graze on both freshwater and saltwater vegetation. They dedicate almost half the day to munching on their food, consuming 10% of their body weight in plant mass daily. Given that a manatee’s weight can reach up to 3,000 pounds, they ingest a substantial amount of vegetation each day.

6. Manatees don’t bite.

Manatees possess a mouthful of teeth but refrain from biting. They employ their teeth to munch on seagrass and other forms of plant life. Manatees stand as significant eaters—the largest herbivores in the ocean, measuring nearly 14 feet in length and weighing up to 3,000 pounds. They devote a substantial portion of their waking hours to eating, consuming 5-10% of their body weight in greenery daily. The act of chewing wears down their teeth, yet manatees consistently grow new teeth throughout their entire lives, akin to their elephant relatives. Nevertheless, manatees only grow new teeth six times during their lifespan. The fresh teeth emerge at the rear, displacing the old ones towards the front.

7. Small, smooth brain.

Manatees have a smooth brain, which is the smallest brain in terms of the ratio of their brain to their body size among all mammals. However, the brain of manatees has similar ins and outs of cortical folds like that of humans and other mammals and boasts considerable cognitive capacity. So the tiny brain does not mean manatees are stupid. And while they may not be as clever as dolphins, manatees can learn to undertake basic tasks.

Experimentally, the animals have been involved in color-differentiating tasks with a lot of success. In terms of communication, the gentle giants communicate with squeaking squealing sounds. Manatees do not make very loud sounds, but they are vocal animals with individual vocalizations. They can make sounds to communicate fear or anger in socializing, and to find each other, such as when a baby calf looks for her mother.

8. Manatees need warm water to survive.

Manatees require warm water. Due to their low metabolic rates and limited fat protection against cold water, they prefer water that maintains a temperature of 72 degrees or higher. Despite their blubbery appearance, they lack sufficient blubber for warmth retention. Although they may seem well-insulated, their body mass primarily consists of their stomach and intestines. Without proper insulation, water temperatures below 68 degrees can lead to cold stress for them. That is why, when winter arrives, they move to warm water outputs from power plants or to the warm spring-fed waters in Kings Bay and Three Sisters Springs, where the water temperature is a consistent 72 degrees. In 2010, at least 246 manatees died in Florida due to cold stress from the colder-than-normal winter.

9. No natural predators.

Manatees have no natural predators in the wild. Humans have played a significant role in placing all three manatee species at risk of extinction. In fact, humans cause about half of West Indian Manatee deaths due to boat collisions. Speeding boats are responsible for the high risk faced by manatees, as they are quite buoyant and use their horizontally placed diaphragm and breathing to control their buoyancy, but their average speed of 3-5 miles per hour makes it difficult for them to escape.

At Captain Mike’s, we invite people to experience Kings Bay and Three Sisters Springs in Crystal River, Florida, which are among the best places in the world to see and snorkel with manatees. When people visit Crystal River, whether for manatee snorkeling or observing the animals from boardwalks, we hope they find the interaction gratifying and carry that experience beyond mere concern, actively contributing to manatee and habitat protection.

We ensure that our visitors comprehend how their actions in the water affect the animals. Therefore, we promote passive observation and interaction with the animals, implying observing without touching. Interaction with the animals is encouraged only when initiated by the animals themselves. Despite their cuddly appearance, the temptation to hug them must be resisted, as touching, disturbing, or harassing these gentle giants can lead to penalties.

By practicing proper manatee etiquette, you can relish your time with the manatees in the water and develop a greater appreciation for them. For more information and facts about manatees and manatee tours in Crystal River, Florida, please visit Captain Mike’s Swimming with the Manatees website.

Rules to Follow When Swimming With Manatees

Manatees are protected animals under the law. First is the Marine Mammal Protection Act of 1972. Second is the Endangered Species Act of 1973. These regulations, enforced by both the United States Federal Government and the State of Florida, unequivocally make it illegal to hunt, capture, harass, or kill manatees. Additionally, manatees benefit from protection under the Florida Manatee Sanctuary Act of 1978. This strictly outlaws any intentional or negligent action that annoys, harasses, molests, or disturbs them. Therefore, strict compliance with the rules to follow when swimming with manatees is essential.

Stringent Regulations.

Manatee protection laws are enforced by the United States Fish & Wildlife Service (USFWS) and the Florida Fish & Wildlife Commission (FWC). These two agencies collaborate to ensure the safety of manatees by preventing any endangerment caused by individuals entering their habitat. In fact, violating a manatee protection law can incur penalties at both the state and federal levels.

For instance, violating state law can result in a maximum fine of $500, imprisonment for up to 60 days, or both. However, for severe violations, such as extreme harassment leading to injury or death, the state of Florida may involve federal authorities. This could lead to fines of up to $50,000, a maximum imprisonment term of 1 year, or both. Government agencies are serious about protecting manatees.

What are the rules to follow when swimming with the manatees?

  1. Float on the water surface and observe the animals passively. Passive observation is the best and recommended way to interact with manatees and all wildlife.

  2. Do not touch the manatees. That is, no matter how excited you are, you must never touch the animals. When they come near you, seeking interaction, refrain from touching them.

  3. Do not disturb or wake up a sleeping animal. These actions can result in a significant fine. Avoid approaching a resting or sleeping manatee, and refrain from cornering or surrounding one.

  4. Chasing, pursuing, riding, or harassing a manatee is prohibited when encountering one in the water near you. This is whether snorkeling, swimming, diving, operating a boat, or paddling. If a manatee attempts to avoid you, do not pursue it for a closer look. Harassment refers to any action that could alter the animals’ natural behavior.

  5. Keep your hands and objects to yourself. Do not snag, grab, hook, hit, pinch, ride, or strike a manatee. Likewise, avoid prodding, poking, or stabbing a manatee with your hands, feet, or any object. Allow the animals space to move and never isolate an individual manatee or separate a calf from its mother.

  6. Refrain from feeding manatees or offering them water. Engaging in these actions can lead to the habituation of manatees to humans. This process may subsequently alter their behavior in the wild and decrease their innate fear of humans and boats. Consequently, this can render them more susceptible to harm.

  7. When a manatee is nearby, avoid excessive splashing and noise. The abrupt noise and splashing can have the effect of startling resting manatees. Furthermore, this situation could potentially place them in a risky position if they become frightened and opt to depart from their secure habitats. Additionally, avoid using scuba gear or devices that could prompt manatees to depart their areas. Instead, employ snorkel gear and remain at the water’s surface passively to observe manatees.

  8. Adhere to the “No Entry – Manatee Refuge” markings; these areas are essential for the animals’ survival. Follow viewing and sanctuary guidelines, respecting directions from manatee volunteers and law enforcement officers. Similarly, avoid touching tags and research equipment, and abstain from actions that might disrupt research activities.

Personal Responsibility.

Manatee protection isn’t solely under the jurisdiction of law enforcement agencies. It is a duty shared by everyone entering or operating in manatee habitats. Ensuring the safety and well-being of these animals falls on each individual to prevent harm, injury, or death. When engaging in activities like snorkeling with manatees, it’s crucial to recognize that your actions carry weight. Disregarding the established rules for swimming with manatees makes you liable and subject to individual charges for your behavior. Strict compliance with rules to follow when swimming with manatees is utmost importance.

At Captain Mike’s, we’re dedicated to ensuring you fully understand and follow the three fundamental rules of snorkeling with manatees. These guidelines encompass several crucial aspects. Firstly, there’s the necessity to minimize splashing noise. Additionally, it’s crucial to move slowly in the presence of the animals. Lastly, it is of the utmost importance to refrain from touching the animals with both hands or on their back and stomach. Our instructional video will demonstrate proper conduct in the water.

Why Do Manatees Migrate?

Manatees are typically migrating animals. During the summer, they inhabit shallow, slow-moving rivers, bays, estuaries, and coastal waters areas. This includes fresh, brackish, or salt water, while they freely travel around the Gulf Coast. In the summer months, manatees are found as far west as Alabama and Louisiana. They even reach as far north as Virginia and the Carolinas.

Evading the Cold

But in winter, from November through March, the water in many areas of the Gulf of Mexico becomes unusually cold (below 70 degrees Fahrenheit). This compels the animals to migrate in search of warm water locations for their survival. The animals travel through passageways until they reach areas with warm water. They mostly find their way into Florida, where the temperature in the springs remains at a constant 72 degrees Fahrenheit throughout the year. In the summer, that temperature may be cooler than the surrounding waters, but in the winter, it is high enough and ideal for manatees.

Need for Warmth

Manatees migrate because they need warm water to survive. A typical manatee weighs half a ton and measures 13 feet long. It maintains relatively little body fat and sustains a very low metabolic rate compared to other marine mammals. Hence, manatees are not able to tolerate temperatures below 68 degrees Fahrenheit for an extended period of time. In fact, individuals affected by the cold are unable to generate sufficient metabolic heat to compensate for the heat lost to the environment. This physiological challenge makes it difficult for them to regulate their body temperature effectively.

Cold Stress Syndrome

Extended exposure to cold temperatures causes a cascade of clinical disease processes called the cold stress syndrome (CSS). This syndrome is characterized by a slow-down in metabolism, leading to digestion problems, reduced appetite and weight loss. As a result, manatees impacted by these conditions experience compromised immunity. This makes them vulnerable to environmental toxins and pathogens that can lead to various diseases. These ailments include intestinal infections, pneumonia, and viral infections. Therefore, chronic exposure to cold is fatal to manatees and predisposes their entire population to danger and decline. Recognizing their vulnerability to cold-related diseases, manatees actively migrate from colder regions and congregate around sources of warm water during the winter months. These sources include natural springs and warm water discharges from power plants.

Fixed Wintering Areas

Interestingly, individual manatees usually return to the same wintering areas year after year. Certainly, this reliance on specific areas is influenced by the locations where their parents introduced them as young calves. Additionally, it is coupled with their ability to remember migration routes between summer and winter seasons. A significant population of manatees frequents the natural springs of Homosassa and Crystal River. Additionally, some manatees are present in the Banana and Indian Rivers, as well as the St. Johns River and the Intracoastal waters along Florida’s east coast.

Manatees have also been known to migrate and gather near power plants. The reason for this is to seek refuge in the warm water outflows from discharge channels. Apart from just providing the warm water these animals seek out in colder months, power plant effluents play a critical role in their protection. In past cold seasons, flocks of more than 500 manatees have been spotted basking in the heated water near power plants. In the past, manatees used to migrate primarily to the relatively warm freshwater springs or move far south to avoid colder waters. However, in recent times, over 60 percent of the population has become accustomed to spending the winter in the vicinity of warm discharges from industrial plants.

When do they migrate?

November is the month when manatees begin their inland migration. It is at this time of the year when manatees search for warm water areas to stay during the duration of the winter and to help them survive the cold. These areas are usually freshwater springs, bays and rivers, and the outflows of power plants. Manatees use canals and rivers as their routes. They are moving between summer and winter months through travel corridors or passageways. This is why boaters and personal watercraft users should be cautious. Also, they slow their speed along these water bodies to avoid harming manatees.

Swimming with Manatees

Crystal River, Florida is one of the areas where manatees migrate during the winter. When the cold season sets in, hundreds of manatees flock the warm water springs where the temperature is a constant 72 degrees Fahrenheit. The larger number of animals huddled together makes it easier for swimmers to find, see and swim with manatees in the winter—though there are also resident manatees that you can find and swim with at any time of year. More importantly, Crystal River is one of the only areas in the world where you can legally interact and snorkel with manatees.

At Captain Mike’s, we offer manatee tours in Crystal River, Florida that are designed to deliver remarkable and gratifying experiences. Our tours are guided by knowledgeable, experienced and certified captains and always guarantee that every person on board sees and snorkels with these gentle creatures. We also respect, protect and care for these animals and their habitat and ensure that all our manatee tours are in line with the latest rules, guidelines and research on the animals.

The 3 Species of Manatees

Manatees are large and gentle creatures with an unmistakable appearance. They are gray and oval-shaped sea giants, with stout bodies, whiskered face, two flippers and a rounded paddle-like tail. They live their entire lives in water, relying almost exclusively on vegetation for their food. Due to a lack of body fat for insulation against cold, they like to stay in water that is at least 60 degrees Fahrenheit or warmer in order to survive. Manatees are solitary animals that prefer to live alone except during mating season or nursing young ones. They move slowly, but can go at quick bursts of speed when necessary.

How many species of manatees exist?

There are three species of manatees. First, the West Indian Manatee that is commonly found in Florida and the Gulf Coast of North America. Next, the Amazonian Manatee that is found in the Amazonian River Basin. And, the West African Manatee found along the tropical and sub-tropical waters of Africa. All three manatee species are aquatic mammals that are large in size and almost wholly herbivorous. And all three species are highly vulnerable and endangered, constantly facing threats such as loss of habitat, entrapment in turbines and generators, entanglement in fishing nets and collisions with watercrafts.

Amazonian Manatee (Trichechus inunguis)

This unique species of manatees is found in the Amazon River Basin and its tributaries. It is the smallest of the three manatee species in terms of size, being 8-10 feet long and weighing about 1,100 pounds. The Amazonian Manatee is the only member of the manatee family that lives exclusively in freshwater and never moves into saltwater. It also has a smooth skin and stands out as the only type of manatee without nails on the forelimbs.

West African Manatee (Trichechus senegalensis)

Found in coastal areas, in both saltwater and freshwater, the West African Manatee commonly resides in the tropical and sub-tropical zones of Western Africa. With a size of 10-13 feet and weight of 1,100 pounds, the West African Manatee is bigger than the Amazonian Manatee, though of similar size and appearance to the West Indian Manatee except for its blunter snout. The manatee is typically herbivorous, but may occasionally feed on small fish and shellfish.

West Indian Manatee (Trichechus manatus)

The West Indian Manatee holds the distinction of being the largest and most well-known Sirenian. It possesses gray, somewhat brown skin, a rounded tail, and a set of nails on its forelimbs. These creatures grow to 13 feet in length and can weigh up to 3,300 pounds. The West Indian Manatee primarily inhabits marshy coastal regions. And, it can be located in the Southeastern United States, Central and South America, the Caribbean, and the Gulf of Mexico. This species encompasses two subspecies: the Florida Manatee and the Antillean Manatee.

Florida Manatee (Trichechus manatus latirostris)

This most recognized group of manatees commonly inhabits the coasts of Southeastern United States and the Gulf of Mexico. In Florida, large numbers of manatees gather in the springs of Crystal River, especially during winter when they search for warmer waters. People from around the world travel to witness these sea giants in their natural habitat. The Florida Manatee surpasses the Antillean Manatee in size. They possess elongated round bodies that taper toward a flat, paddle-shaped tail. Their head and face exhibit wrinkles with whiskers on the snout.

Antillean Manatee (Trichechus manatus manatus)

This subspecies of the West Indian Manatee inhabits the Caribbean and the Coast of Central America. They maintain a close relationship with manatees found along Florida’s coast. Nonetheless, their size is smaller compared to Florida manatees. They can grow up to 12 feet in length and reach weights of up to 3000 pounds, although more commonly around 9-10 feet and 1,000 pounds. Their primary diet consists of sea grass, and they dedicate several hours per day to grazing, displaying a slow-paced nature. Historically, locals hunted Antillean manatees for food, selling them to explorers. Presently, these manatees confront numerous threats, including habitat loss, vessel strikes, entanglement in fishing gear, and poaching.

At Captain Mike’s, we treasure manatees and are committed to helping others learn about them and care for these amazing but endangered creatures. We offer guided manatee tours in Crystal River and take part in efforts to protect the animals. A ride with us through the springs and an hour or more in the water with manatees will give you memories for a lifetime. Want to know more about manatees and manatee tours in Crystal River, Florida?

8 Surprising Facts About Manatees

Many people are aware that a manatee is a large, slow-moving creature often referred to as a sea cow. However, only a few individuals are familiar with the manatee’s true friendliness, intelligence, and engaging nature. Nevertheless, those who have had the opportunity to interact with this gentle giant possess a more profound understanding. In this context, we are presenting eight surprising facts about this endangered species that could catch you by surprise.

1. Manatees have been spotted as far north as Cape Cod. Their most common habitat is the waters around Florida and the Caribbean. However, manatees have been observed off the coast of Massachusetts in rare instances. This is a very impressive feat since manatees usually travel at about 5 mph.

2. They have a never-ending supply of teeth. Unlike humans, manatees continually develop new teeth throughout their lives. This adaptation proves valuable as their diet accelerates tooth wear and loss. Fortunately, their amiable nature ensures that these teeth never pose a threat to humans.

3. Elephant is the closest relative of manatees. Believe it or not, the world’s largest land animal shares the closest living land relation with a marine mammal. Manatees also have four nails at the tips of their flippers, resembling the toenails on an elephant’s feet.

4. Manatees eat 10 percent of their body weight every day. A fully grown adult manatee weighs between 1,000 and 1,200 pounds. This weight range enables them to consume up to 200 pounds of food each day. This is especially impressive given that their diet is mostly ocean vegetation. For comparison, imagine an average person eating up to 20 pounds of seaweed a day!

5. They have the smallest brain-to-body size ratio of any mammal. Certainly, manatees possess a relatively small brain in relation to their body size. Nevertheless, this should not be equated with them being unintelligent. In fact, manatees have demonstrated certain problem-solving abilities akin to those observed in dolphins. Moreover, individuals who have swum alongside manatees would readily confirm that these friendly mammals display remarkable intelligence.

6. People are the biggest threat to these wonderful creatures. Manatees do not have any natural predators. But, this does not mean they are totally safe. Collisions with boats claim the lives of many manatees every year. Largely because of these collisions, human activity is the biggest threat to manatees.

7. Manatees can be picky about their water. Similar to many individuals, manatees prefer warm water for swimming. Furthermore, despite their substantial size, manatees are unable to endure colder temperatures. As a result, during the cooler winter months, manatees are inclined to search for warm spring-fed water sources to maintain their body temperature. Notably, locations like Crystal River, Florida, witness substantial gatherings of manatees in their waters during this time, as the animals seek warmth. In this area, both tourists and residents have the unique opportunity to swim alongside manatees. They can affectionately enjoy interactions with these gentle creatures.

8. Christopher Columbus mistook manatees for mermaids. During his voyages to the New World, Columbus claimed to spot several mermaids in the waters of what is now the Caribbean. However, it appears that his extended time at sea might have influenced his perceptions. Today, evidence demonstrates that these were, indeed, manatees. Columbus had mistaken manatees for mermaids.

As a bonus fact, if you find manatees intriguing, you might find it pleasing to know that you can swim and interact with them. Places like Captain Mike’s Swimming with the Manatees at King’s Bay in Crystal River, Florida, provide people with the opportunity to swim alongside these captivating and friendly animals in their natural habitat.

12 Things You Didn’t Know about Manatees

Manatees are large, with a grey-brown color and elongated shape. They are marvelous aquatic mammals that inhabit river and coastal areas’ brackish, freshwater, or marine systems. Manatees are often found in shorelines with seagrass, eelgrass, and other vegetation. They feed on both submerged and floating vegetation, dedicating a significant part of their day to grazing. Due to their inability to endure temperatures under 68 degrees, manatees typically migrate to warm natural springs and power plant outfalls every November. This move ensures their survival during the winter cold. But when summer returns, they expand their range, traveling up to hundreds of miles away, along shorelines and water channels.

Now let us look at some 12 Things You Didn’t Know about Manatees:

  1. The word “manatee” is derived from “manati”, a Carab word that means “breast, udder.” Manatees are also called “sea cows” because they are big in size, graze patiently for hours, feed on a wide variety of grasses, and like to loll around their habitat.
  2. Manatees are the largest herbivore in the ocean. An adult manatee can be as long as 13 feet and as heavy as 1,300 pounds. Each day, a manatee eats 10-15 percent of its weight in vegetation.
  3. Generally, a manatee swims at a speed of 5 mph. But the animal will use its powerful tail to swim at 15 mph in short bursts when threatened or in any situation that calls for increased speed.
  4. Manatees come in three species: Amazonian (T. inunguis), West Indian (T. manatus) and West African (T. senegalensis). They belong to the genus Trichechus and the order Sirenia. The order also includes close manatee cousins such as the Steller’s sea cow (hunted to extinction by 1768) and the dugong (Dugong dugon).
  5. Sailors often thought manatees were mermaids. For instance, Christopher Columbus recorded in his ship log of Jan. 9, 1493, that he saw three mermaids arise from the sea, but concluded the mermaids were not as beautiful as people had said because their faces carried some masculine traits. However, those “mermaids” seen by Columbus were not as beautiful because they were actually manatees.
  6. Manatees replace 90 percent of all the air in their lungs in just one breath, as opposed to humans who replace only 10 percent in a breath. Similarly, the sea giants surface every 3-5 minutes to breathe, but they can also hold their breath and stay submerged for 15-20 minutes.
  7. Manatees are a protected species by both state and federal laws. The Manatee Sanctuary Act declares it illegal to molest, annoy, disturb, harass, or attempt to harass, molest, or disturb an endangered animal. This prohibition applies at any time and in any manner, negligently or intentionally, using any means. Therefore, under the law, riding these animals during your manatee tours can result in arrest and charges for distressing an endangered animal.
  8. Manatees are very closely related to the elephant and the hyrax. In fact, while almost all other animals have a heart with a pointed bottom, manatees and elephants have a heart with a rounded bottom.
  9. Manatees are threatened by a wide variety of things. These include run-ins with watercraft, toxic red tides, entanglement in fishing gear, and habitat loss. About 20 percent of all annual manatee deaths come from collisions with speedboats.
  10. Manatees have 3,000 vibrissae (thick, whisker-like hairs) on their bodies and 2,000 such hairs on their faces. The vibrissae help manatees to sense and explore their surroundings.
  11. Manatees have one of the smallest and smoothest brains of all mammals. That does not mean they are stupid. In fact, recent studies show that manatees are just as clever as dolphins in experimental tasks, although they move slower, are more difficult to motivate and have no taste for fish.
  12. Manatees see in green, blue and gray colors, but never in red. They are nearsighted and have a problem detecting objects until the objects are very close to them.

Facts About Manatees

Having been captivated by enchanting tales of manatees, you’re now more curious than ever. A strong desire has awakened within you to learn more about captivating facts about manatees, and the idea of embarking on a manatee tour to witness them up close and swim alongside them is taking hold in your mind. However, before you set out on this thrilling adventure, you’re diligently seeking accurate and trustworthy facts about manatees.

What are manatees?

Manatees, captivating sea creatures, have a big size with a flat tail, an egg-shaped head, and noticeable flippers. They can be 8 to 13 feet long (2.4 to 4 meters) and weigh around 440 to 1,300 pounds (200 to 590 kg). With their strong tails, manatees skillfully move through water, usually swimming at about 8 km/h (5 mph). But if needed, they can quickly reach 24 km/h (15 mph) for short bursts.

Why are they called sea cows?

It’s true, manatees aren’t connected to cows at all. However, due to some similar features, they’ve earned the name “sea cows.” Like cows, manatees are big, slow-moving animals. These sea-dwelling creatures calmly graze around their home for hours, munching on various plants they find tasty. This is just like how cows act, right? Manatees also relax and take naps in their habitat, similar to cows.

What of their relationship with elephants?

People believe that manatees and elephants come from the same beginnings. They both evolved from small, four-legged animals that were similar to rodents and had hooves, over a long time of 60 million years. Manatees adapted to life in water, while elephants became land animals. When it comes to their closest relatives, manatees belong to a big group of four sea cows in the Sirenia order. This group includes the Dugong, West Indian, West African, and Amazonian manatee. Sadly, the fifth member of this group, the Stellar’s sea cow, disappeared about 250 years ago.

  • Subspecies — Florida manatee (T. manatus latirostris)
  • Antillean manatee (T. manatus manatus)

What’s the difference between manatees and dugongs?

Manatees and dugongs share the same Sirenia order, but they belong to different families. Dugongs are part of the Dugongidae family, while manatees are in the Trichechidae family. Dugongs possess tusks and a tail notch, and they make their home in the Pacific and Indian oceans.

Where are manatees found?

Normally, manatees inhabit oceans, seas, and rivers along the coastlines of various countries. For example, the West Indian manatee resides in the eastern and southern United States. However, a few members of the species have been discovered as far as the Bahamas. The African manatee lives along the rivers and coasts of western Africa. On the other hand, the Amazonian manatee occupies the drainage of the Amazon River. This is ranging from the waters of Peru, Ecuador, and Colombia to the Amazon’s entrance in Brazil.

What are their characteristic habits?

Manatees are typically solitary creatures, although they can occasionally be seen in pairs and very rarely in groups. Being non-territorial animals, manatees don’t require leaders or followers. Therefore, when they come together in a group, it’s often due to mating or congregating in warm areas abundant with vegetation. These gatherings of manatees are referred to as aggregations. Each aggregation usually consists of no more than six individuals.

What do they eat?

Manatees, herbivorous mammals, dedicate numerous hours each day to grazing. Within a 24-hour span, a manatee consumes up to 1/10 of its weight, which is roughly 59 kg or 130 pounds. In marine environments, they graze on sea grasses, while in rivers, they consume freshwater vegetation. Additionally, they partake in feeding on algae.

How do they reproduce?

Female manatees achieve sexual maturity by the age of five, while males require nearly twice that time to become sexually mature. During the mating process, a mature cow (female manatee) is trailed through the water by 6-12 or more bulls (male manatees). This collection of males is termed a mating herd. After a bull mates with a cow, it plays no further role in the calf’s upbringing. However, the cow carries the pregnancy for 12 months and delivers the offspring underwater. Shortly after birth, the mother brings the calf to the water’s surface for air. Cows also ensure that their calves can swim within an hour or so after being born.

What’s their conservation status?

All manatee species are confronting a significant risk of extinction, with a high level of endangerment or vulnerability. The total manatee population is anticipated to decrease by approximately 30 percent within the next 20 years. While the precise count of existing manatees remains unknown, the current Amazonian manatee population stands at around 10,000 animals, whereas African manatees number fewer than 10,000. In the wild, there are up to 6,300 Antillean manatees and 6,620 Florida manatees, representing a substantial rise from the initial count of 2,500 mature animals for each subspecies when they were initially classified as endangered decades ago.

On March 31, 2017, the U.S. FWS (Fish & Wildlife Service) reclassified the status of the West Indian manatee from “Endangered” to “Threatened” due to notable habitat enhancements and a resurgence in manatee populations. However, these creatures still encounter severe threats owing to their slow reproductive rates, habitat loss resulting from waterfront development, fishing nets that traverse their habitats in West Africa and the Amazon, as well as collisions with speedboats. In West Africa, manatees are still pursued for their meat.

Other Critical Facts About Manatees

  1. The term “manatee” originates from “manati,” a word meaning “breast.” This term comes from the Taino people, who inhabited the Caribbean before Columbus.
  2. Manatees possess small eyes, yet they have excellent eyesight. A small membrane is drawn over the eyeball to protect it.
  3. Massive inner ear bones and good hearing capacity are found in manatees, despite the absence of outer ear structures.
  4. Manatees continuously replace their grinding molars, their sole teeth, throughout their lives as they adapt to their diet of abrasive plants.
  5. Due to having only 6 neck vertebrae, manatees cannot move their heads sideways. To look behind, a manatee must rotate its entire body. In comparison, many other mammals, like giraffes, possess 7 neck vertebrae.
  6. Manatee skin often becomes covered with algae.
  7. Manatees never inhabit or venture onto land.
  8. Manatees can hold their breath underwater for several minutes. While resting, they surface for air approximately every 15 minutes. During swimming, they raise their noses above the water’s surface every few minutes to breathe.

3 Important Things to Remember Before Swimming With The Manatees

They may not be as agile and elegant as dolphins or as strong and graceful as killer whales, but an encounter with manatees can be one of the most profound, memorable and gratifying experiences in your life. So big yet so tender, manatees will glide slowly toward you once they notice you in their habitat. Watching manatees use their paddle-like tails to move their 12-foot-long bodies gracefully through the water is a unique, exciting and unforgettable experience.

You will enjoy every minute spent in the company of these animals in the waters of Crystal River, floating over the marvelous natural springs and watching the manatees graze, come to the water surface for air and just go about their normal lives. Being close to these sea cows is not only fascinating and fun, but also a rare opportunity to interact with an endangered animal in its habitat.

Entering the water

Manatees are endangered and protected animals. So regardless of how thrilled and excited you are, you must enter the water slowly to avoid disturbing them. Remember that as you descend in the water, some manatees will be paddling around slowly, some still sleeping while others will be going about their everyday lives. You must keep the splash noise to a minimum, make very slow movements and try to limit the amount of sediment that may rise from the river bed.

If you see any manatees, do not chase or approach them. Just remain still in the water, observe from above on the surface and at a distance. Let the animals approach you. You must never prod, poke, ride, capture, harass, step on or feed manatees. By observing quietly and passively, you will get the rare chance to observe the natural behavior of these mammals. In fact, manatees are so social that they will come to you on their own.

3 Important Things to Remember Before Swimming with the Manatees

Swimming or snorkeling is a wonderful way to enjoy your time with these rare animals and to relish the 72-degree flowing springs of Crystal River. Manatees avoid scuba bubbles, so swimming is the best way for people of all ages to intermingle with them. However, once you enter the water, there are three important rules to follow to get the best experience and avoid potential fines.

1. Don’t dive down on a manatee

Swimming with manatees must never disturb or harm the animals. Once you get in the water, you must remain floating on the surface with very slow movements and no splash noise. This is why you are provided with a wetsuit to make you buoyant and keep you on the surface. If you see a manatee, just look but do not try to touch. Trying to swim toward a manatee may generate excess splashing and noise that will disturb manatees.

You also may scare some of them away from their warm water areas into cold water or the path of a nearby vessel. Be still in the water, acting as if you do not have feet. If a manatee chooses to flee or move away from you, do not chase or approach the animal. The manatee may go off and then come back to you, which would be a wonderful experience. It is okay to swim toward a manatee, but you must only do so gently and quietly. There is a $500 fine if you breach this rule.

2. Don’t chase manatees

Swimming with these adorable creatures can bring so much pleasure if you just remain still on the water surface, cause no disturbance and watch from above. If the animals get anxious or sense danger, they will flee and avoid contact. It is absolutely forbidden to ride, chase or harass manatees. You should just float quietly and wait from a distance for the manatees to approach you. Don’t try to touch the manatee. You must never wear fins or use scuba gear as manatees prefer the absence of bubbles. Remain motionless in the water, watch and wait. These curious creatures will approach you for an interaction. And you will love it.

3. Don’t enter manatee sanctuaries

You must never enter designated manatee sanctuaries for any reason. Sanctuaries are roped off and protected areas, with no waterborne activities allowed. They are off-limits to any human activities like diving, swimming, boating and fishing. The sanctuaries are set aside based on scientific evidence, which identifies them as critical areas for manatee survival, especially as feeding areas or warm water habitats. It is in these sanctuaries where manatees typically feed, rest and sleep undisturbed. If you see a manatee inside a roped-off sanctuary, just observe from a distance. Your captain will ensure that you know what a sanctuary is and avoid any activities in these areas.

Things You Need to Know Before Swimming With The Manatees

With an abundance of manatees, Florida is a great destination for those looking to see, swim and snorkel with these gentle sea mammals. Beginning as early as 6:30 a.m., when it is still dark and the water so cold, manatee tours attract heavy fanfare as adventurers climb into boats in the fog and the captains insist on passive observation, telling tourists to lie still in the waters and wait for manatees to come to them. The lumbering sea cows are curious animals and tend to hang out with people as long as they are treated tenderly. So what key things should you know before swimming with the manatees?

1. Swimming with manatees best in the winter

Though many people consider Florida a hot spring break destination, it is in the winter when West Florida is ideal for snorkeling with manatees. Throughout the winter, the springs of King’s Bay and Crystal River enjoy a warm temperature of 72 degrees and attract hundreds of manatees, making it the best time to see and swim with these gentle giants. The largest number of West Indian manatees head to Crystal River between November and April, so if you want a successful tour this is ideal time to go. However, you need to book in advance for your tour as peak season tours tend to fill up quickly.

2. Mandatory rules when swimming with manatees

Manatees are protected animals and there are laws to guarantee their safety. Therefore, your interactions with them must be limited. The laws are enforced strictly and must be adhered to by everyone who interacts with them. You should go over the rules and master the dos and don’ts when you swim with manatees. Remember you are a guest in the home of endangered animals and it is a privilege to share their habitat. So treat them with utmost respect. As a rule, stick to passive observation.

3. Number of daily manatee sightings varies

Manatees are not restricted to a specific area and are free to roam the waters as they wish. So no two days are the same and the numbers of manatees you will see are different. The weather, time of the year and tidal influences also affect the conditions daily making it difficult to predict the number of manatees you can see on any day. It is important to note that the unique ecosystem of Florida makes it a prime habitat for manatees and ensures that there is a resident population of manatees throughout the year. The permanent population makes Crystal River and other locations in Florida ideal for swimming with manatees even during warmer summer months.

4. Work with in-water manatee tour guides

Most manatee tour companies provide knowledgeable and skilled in-water guides to help tourists observe the laws and requisite guidelines when swimming with manatees. Make sure to work with a guide from the start of your manatee swim to the end. This will ensure you have a safe, pleasant and educational experience and give the animals maximum respect while in their habitat.

5. Options of boat ride or swim

It is not a must that you get into the water and swim. You are free to ride on a boat and observe manatees from a distance. Most likely the manatees will come close to your boat. So if you do not want to endure the cold water in the winter, you can just carry your cameras and binoculars and use a boat to navigate the surroundings of your refuge.

Swimming with manatees can give you an unforgettable vacation. You just need to plan well, book in advance and work with a reputable tour provider. For more information, visit the site Swimming with the Manatees.
