Manatees (family Trichechidae, genus Trichechus) are large, fully aquatic, mostly herbivorous marine mammals sometimes known as sea cows. There are three accepted living species of Trichechidae, representing three of the four living species in the order Sirenia: the Amazonian manatee (Trichechus inunguis), the West Indian manatee (Trichechus manatus), and the West African manatee (Trichechus senegalensis). They measure up to 4.0 metres (13.1 ft) long, weigh as much as 590 kilograms (1,300 lb),[2] and have paddle-like flippers. The etymology of the name is dubious, with connections having been made to Latin "manus" (hand), and to a word sometimes cited as "manati" used by the Taíno, a pre-Columbian people of the Caribbean, meaning "breast".[3] Manatees are occasionally called sea cows, as they are slow plant-eaters, peaceful and similar to cows on land. They often graze on water plants in tropical seas.[4]

  • ✪ How To Draw A Cartoon Manatee


Welcome to the Crystal River National Wildlife Refuge and the Kings Bay Manatee Refuge. You are among the thousands of yearly visitors privileged to enter our natural springs, home of the Florida manatee. Your awareness of our rules and recommendations is essential to the protection of manatees and their ecosystem. It is your responsibility to learn and understand these rules prior to recreating in the Refuge. Between November and April, Kings Bay is home to the largest aggregation of manatees in a natural environment in the world. To protect manatees from harm, harassment and disturbance, the Crystal River National Wildlife Refuge and Manatee Sanctuaries were created in parts of Kings Bay. In addition, all of Kings Bay has been designated as a federal manatee protected area with special manatee protection regulations in place year-round The Florida manatee is protected by the Federal Endangered Species Act of 1973, the Marine Mammal Protection Act of 1972 and the Florida Manatee Sanctuary Act of 1978. Violations of these statutes may result in fines of up to $100,000 and/or 1 year in jail. The US Fish and Wildlife Service recommends that all visitors practice passive observation when viewing manatees. Passive observation means calmly observing manatees from a distance and from the surface of the water, and not initiating any contact with the manatee. In addition to practicing passive observation, visitors should not approach manatees, particularly those found resting. During the winter months, manatees come to the springs to stay warm, and spend the majority of their time resting around Kings Bay. Undisturbed access to the springs is critical to the manatees’ survival. Resting manatees can be found near the water’s surface, partially submerged in the water column or laying on the water bottom. They remain relatively still while resting, but may make some slight movements. For example: Manatees may remain almost motionless before moving to the surface to breath, then returning to the original resting position This means that resting manatees may be found moving while resting and it is your responsibility not to disturb them. Manatees are completely defenseless wild animals. Recreating close to manatees is a privilege that comes with serious personal responsibility. In the next few minutes, the rules that prevent manatee harassment will be shown, followed by additional recommendations that will improve the quality of your experience. Manatee sanctuaries provide a safe area for manatees to rest without disturbance from humans during the cold winter months. Manatee sanctuaries are designated by large orange and white buoys stating closed area. All activities are prohibited inside. Visitors must stay out of all posted manatee sanctuaries and all other posted closed areas. The following activities or the attempt to perform any of the following activities is prohibited throughout Kings Bay: Chasing or pursuing a manatee Disturbing or touching a resting or feeding manatee Diving from the surface onto a resting or feeding manatee Cornering or surrounding a manatee Riding, holding, grabbing, or pinching a manatee Poking, prodding, or stabbing a manatee with anything, including your hands and feet Standing or stepping on a manatee Separating a mother and calf or separating a manatee from a group Giving a manatee anything to eat or drink Actively initiating contact with a belted or tagged manatee and associated gear, including any belts, harnesses, tracking devices, or antennae Interfering with rescue and research activities We understand that these are extensive rules to remember; however, if you practice passive observation you won’t have to worry about breaking any of these rules. Responsibilities of swimmers, snorkelers, and divers in Kings Bay There are other things you can do that will improve the quality of your experience and reduce impacts to manatees and other visitors. By following these simple guidelines, you will prevent manatee harassment and disturbance while increasing your opportunity to see manatees up close. When you are ready to get in the water, remember that you are about to enter the manatee’s home. Make sure there is a dive flag within 100’ of where you’ll be swimming. Enter the water quietly and slowly to keep from scaring manatees and stirring up the bottom. Unnecessary splashing can disturb manatees and stir up sediment, reducing visibility Keep your feet/fins off the bottom, especially in shallow areas, to maintain visibility. Always keep calm, reduce splashing or excessive noise as much as possible. When approaching the springs, swim as quietly and slowly as possible, keeping legs, arms, hands and fin movements to a minimum and below the water’s surface to prevent splashing. A wetsuit and snorkel gear is highly recommended, especially during the winter months. Wetsuits provide improved buoyancy, helping keep all snorkeling activity at the surface Snorkel gear improves your ability to see manatees, and will prevent you from accidentally swimming over or into manatees. Always give manatees the right of way and do not block or intercept a manatee as it moves or surfaces to breathe. Avoid swimming over manatees or hovering over them. Swimming over or hovering over manatees can easily disturb them, particularly those found resting, nursing or feeding. Don’t approach a mating herd. Although manatees aren’t aggressive, approaching a herd can be dangerous for swimmers. The sound of bubbles generated by scuba gear may disturb manatees. Avoid approaching any manatee while wearing scuba gear. Remember, you are responsible for your children. Make sure that they understand the rules for swimming with manatees and never leave them unattended while in the water. Practice passive observation. By using this technique, the likelihood of harassing or disturbing a manatee is significantly reduced, and manatees are more likely to approach you. Your actions affect the behavior of other visitors around you; so it is always best to be the example, especially when around children. If you see an injured manatee or need to report a violation of the Kings Bay manatee regulations, please call the Florida Fish and Wildlife Conservation Commission’s Wildlife Alert Hotline at 1 888 404-3922. Thank you for taking the time to review these regulations and guidelines. Please remember that Kings Bay is a community shared by manatees and people, so be respectful of homeowners, businesses, and manatees during your visit. The USFWS wants both: you and the manatees to have a safe experience. With your help, we can protect this critical manatee area so it can be shared with future generations For more information about manatee protection within Kings Bay, visit us online at



Manatees are three of the four living species in the order Sirenia. The fourth is the Eastern Hemisphere's dugong. The Sirenia are thought to have evolved from four-legged land mammals more than 60 million years ago, with the closest living relatives being the Proboscidea (elephants) and Hyracoidea (hyraxes).[5]

The Amazonian's hair color is brownish gray, and it has thick wrinkled skin, often with coarse hair, or "whiskers". Photos are rare; although very little is known about this species, scientists think it is similar to West Indian manatee.

Manatees weigh 400 to 550 kilograms (880 to 1,210 lb), and average 2.8 to 3.0 metres (9.2 to 9.8 ft) in length, sometimes growing to 4.6 metres (15 ft) and 1,775 kilograms (3,913 lb) (the females tend to be larger and heavier). At birth, baby manatees weigh about 30 kilograms (66 lb) each. The manatee has a large, flexible, prehensile upper lip, used to gather food and eat and for social interaction and communication. Manatees have shorter snouts than their fellow sirenians, the dugongs. The lids of manatees' small, widely spaced eyes close in a circular manner. The adults have no incisor or canine teeth, just a set of cheek teeth, which are not clearly differentiated into molars and premolars. These teeth are repeatedly replaced throughout life, with new teeth growing at the rear as older teeth fall out from farther forward in the mouth, somewhat as elephants' teeth do.[6][7] At any time, a manatee typically has no more than six teeth in each jaw of its mouth.[7] Its tail is paddle-shaped, and is the clearest visible difference between manatees and dugongs; a dugong tail is fluked, similar in shape to that of a whale. The female manatee has two teats, one under each flipper,[8] a characteristic that was used to make early links between the manatee and elephants.

The manatee is unusual among mammals in having just six cervical vertebrae,[9] a number that may be due to mutations in the homeotic genes.[10] All other mammals have seven cervical vertebrae,[11] other than the two-toed and three-toed sloths.

Like the horse, the manatee has a simple stomach, but a large cecum, in which it can digest tough plant matter. Generally, the intestines are about 45 meters, unusually long for an animal of the manatee's size.[12][better source needed]

Apart from mothers with their young, or males following a receptive female, manatees are generally solitary animals.[7] Manatees spend approximately 50% of the day sleeping submerged, surfacing for air regularly at intervals of less than 20 minutes. The remainder of the time is mostly spent grazing in shallow waters at depths of 1–2 metres (3.3–6.6 ft). The Florida subspecies (T. m. latirostris) has been known to live up to 60 years.


Generally, manatees swim at about 5 to 8 kilometres per hour (3 to 5 mph). However, they have been known to swim at up to 30 kilometres per hour (20 mph) in short bursts.[13]

Intelligence and learning

Manatees are capable of understanding discrimination tasks and show signs of complex associative learning. They also have good long-term memory.[14] They demonstrate discrimination and task-learning abilities similar to dolphins and pinnipeds in acoustic and visual studies.[15]


Manatees typically breed once every two years; generally only a single calf is born. Gestation lasts about 12 months and to wean the calf takes a further 12 to 18 months.[7]


Manatees emit a wide range of sounds used in communication, especially between cows and their calves. Their ears are large internally but the external openings are small, and they are located four inches behind each eye.[16] Adults communicate to maintain contact and during sexual and play behaviors. Taste and smell, in addition to sight, sound, and touch, may also be forms of communication.[17]


Manatees are herbivores and eat over 60 different freshwater (e.g., floating hyacinth, pickerel weed, alligator weed, water lettuce, hydrilla, water celery, musk grass, mangrove leaves) and saltwater plants (e.g., sea grasses, shoal grass, manatee grass, turtle grass, widgeon grass, sea clover, and marine algae). Using their divided upper lip, an adult manatee will commonly eat up to 10%–15% of their body weight (about 50 kg) per day. Consuming such an amount requires the manatee to graze for up to seven hours a day.[18] To be able to cope with the high levels of cellulose in their plant based diet, manatees utilize hindgut fermentation to help with the digestion process.[19] Manatees have been known to eat small numbers of fish from nets.[20]

Feeding behavior

Manatees use their flippers to "walk" along the bottom whilst they dig for plants and roots in the substrate. When plants are detected, the flippers are used to scoop the vegetation toward the manatee's lips. The manatee has prehensile lips; the upper lip pad is split into left and right sides which can move independently. The lips use seven muscles to manipulate and tear at plants. Manatees use their lips and front flippers to move the plants into the mouth. The manatee does not have front teeth, however, behind the lips, on the roof of the mouth, there are dense, ridged pads. These horny ridges, and the manatee's lower jaw, tear through ingested plant material.[18]


Manatees have four rows of teeth. There are 6 to 8 high-crowned, open-rooted molars located along each side of the upper and lower jaw giving a total of 24 to 32 flat, rough-textured teeth. Eating gritty vegetation abrades the teeth, particularly the enamel crown; however, research indicates that the enamel structure in manatee molars is weak. To compensate for this, manatee teeth are continually replaced. When anterior molars wear down, they are shed. Posterior molars erupt at the back of the row and slowly move forward to replace these like enamel crowns on a conveyor belt, similarly to elephants. This process continues throughout the manatee's lifetime. The rate at which the teeth migrate forward depends on how quickly the anterior teeth abrade. Some studies indicate that the rate is about 1 cm/month although other studies indicate 0.1 cm/month.[18]


Range and habitat

Manatees inhabit the shallow, marshy coastal areas and rivers of the Caribbean Sea and the Gulf of Mexico (T. manatus, West Indian manatee), the Amazon basin (T. inunguis, Amazonian manatee), and West Africa (T. senegalensis, West African manatee).[21]

West Indian manatees prefer warmer temperatures and are known to congregate in shallow waters. They frequently migrate through brackish water estuaries to freshwater springs. They cannot survive below 15 °C (60 °F). Their natural source for warmth during winter is warm, spring-fed rivers.

West Indian

The coast of the state of Georgia is usually the northernmost range of the West Indian manatees because their low metabolic rate does not protect them in cold water. Prolonged exposure to water below 20 °C (68 °F) can cause "cold stress syndrome" and death.[22]

Florida manatees can move freely between fresh water and salt water.

Manatees have been seen as far north as Cape Cod, and in 1995[23] and again in 2006, one was seen in New York City[24] and Rhode Island's Narragansett Bay. A manatee was spotted in the Wolf River harbor near the Mississippi River in downtown Memphis in 2006, and was later found dead 10 miles downriver in McKellar Lake.[25]

The West Indian manatee migrates into Florida rivers—such as the Crystal, the Homosassa, and the Chassahowitzka rivers, whose headsprings are 22 °C (72 °F) all year. In November to March, about 400 West Indian manatees (according to the National Wildlife Refuge) gather in the rivers in Citrus County, Florida.[citation needed]

In winter, manatees often gather near the warm-water outflows of power plants along the Florida coast, instead of migrating south as they once did. Some conservationists are concerned that these manatees have become too reliant on these artificially warmed areas.[26] The U.S. Fish and Wildlife Service is trying to find a new way to heat the water for manatees that depended on plants that have closed. The main water treatment plant in Guyana has four manatees that keep storage canals clear of weeds; there are also some in the ponds of the national park in Georgetown, Guyana.

Studies suggest that Florida manatees need access to fresh water for proper regulation of water and salts in their bodies.

Accurate population estimates of the Florida manatee (T. manatus) are difficult. They have been called scientifically weak[27] because they vary widely from year to year, some areas showing increases, others decreases, and little strong evidence of increases except in two areas. Manatee counts are highly variable without an accurate way to estimate numbers: In Florida in 1996, a winter survey found 2,639 manatees; in 1997, a January survey found 2,229, and a February survey found 1,706.[15] A statewide synoptic survey in January 2010 found 5,067 manatees living in Florida, the highest number recorded to that time.[28]

As of January 2016, the USFWS estimates the range-wide manatee population to be at least 13,000; as of January, 2018, at least 6,100 are estimated to be in Florida.[29][30]

Population viability studies conducted in 1997 found that decreasing adult survival and eventual extinction were a probable future outcome for Florida manatees unless they got more protection.[31] The U.S. Fish and Wildlife Service proposed downgrading the manatee's status from endangered to threatened in January 2016 after more than 40 years of the manatee's being classified as on the endangered.[32]

Fossil remains of Florida manatee ancestors date back about 45 million years.[citation needed]


The freshwater Amazonian manatee (T. inunguis) inhabits the Amazon River and its tributaries, and never ventures into salt water.[33]

West African

They are found in coastal marine and estuarine habitats, and in freshwater river systems along the west coast of Africa from the Senegal River south to the Cuanza River in Angola. They live as far upriver on the Niger River as Koulikoro in Mali, 2,000 km from the coast.[34]


Overall, predation does not present a significant threat to the survival of any manatee species.[citation needed]

Relation to humans

The main causes of death for manatees are human-related issues, such as habitat destruction and human objects. Natural causes of death include adverse temperatures, predation by crocodiles on young,[35] and disease.[citation needed]

Ship strikes

Their slow-moving, curious nature, coupled with dense coastal development, has led to many violent collisions with propeller-driven boats and ships, leading frequently to maiming, disfigurement, and even death. As a result, a large proportion of manatees exhibit spiral cutting propeller scars on their backs, usually caused by larger vessels that do not have skegs in front of the propellers like the smaller outboard and inboard-outboard recreational boats have. They are now even identified by humans based on their scar patterns. Many manatees have been cut in two by large vessels like ships and tug boats, even in the highly populated lower St. Johns River's narrow channels. Some are concerned that the current situation is inhumane, with upwards of 50 scars and disfigurements from vessel strikes on a single manatee.[36] Often, the lacerations lead to infections, which can prove fatal. Internal injuries stemming from being trapped between hulls and docks and impacts have also been fatal. Recent testing[citation needed] shows that manatees may be able to hear speed boats and other watercraft approaching, due to the frequency the boat makes. However, a manatee may not be able to hear the approaching boats when they are performing day-to-day activities or distractions. The manatee has a tested frequency range of 8 kilohertz to 32 kilohertz.[citation needed]

Manatees hear on a higher frequency than would be expected for such large marine mammals. Many large boats emit very low frequencies, which confuse the manatee and explain their lack of awareness around boats. The Lloyd's mirror effect results in low frequency propeller sounds not being discernible near the surface, where most accidents occur. Research indicates that when a boat has a higher frequency the manatees rapidly swim away from danger.[37]

In 2003, a population model was released by the United States Geological Survey that predicted an extremely grave situation confronting the manatee in both the Southwest and Atlantic regions where the vast majority of manatees are found. It states,

In the absence of any new management action, that is, if boat mortality rates continue to increase at the rates observed since 1992, the situation in the Atlantic and Southwest regions is dire, with no chance of meeting recovery criteria within 100 years.[38]

"Hurricanes, cold stress, red tide poisoning and a variety of other maladies threaten manatees, but by far their greatest danger is from watercraft strikes, which account for about a quarter of Florida manatee deaths," said study curator John Jett.[39]

According to marine mammal veterinarians:

The severity of mutilations for some of these individuals can be astounding – including long term survivors with completely severed tails, major tail mutilations, and multiple disfiguring dorsal lacerations. These injuries not only cause gruesome wounds, but may also impact population processes by reducing calf production (and survival) in wounded females – observations also speak to the likely pain and suffering endured.[15] In an example, they cited one case study of a small calf "with a severe dorsal mutilation trailing a decomposing piece of dermis and muscle as it continued to accompany and nurse from its mother ... by age 2 its dorsum was grossly deformed and included a large protruding rib fragment visible."[15]

These veterinarians go on to state:

[T]he overwhelming documentation of gruesome wounding of manatees leaves no room for denial. Minimization of this injury is explicit in the Recovery Plan, several state statutes, and federal laws, and implicit in our society's ethical and moral standards.[15]

In 2009, of the 429 Florida manatees recorded dead, 97 were killed by commercial and recreational vessels, which broke the earlier record number of 95 set in 2002.[40][41]

Red tide

Another cause of manatee deaths are red tides, a term used for the proliferation, or "blooms", of the microscopic marine algae, Karenia brevis. This dinoflagellate produces brevetoxins that can have toxic effects on the central nervous system of animals.[42]

In 1996, a red tide was responsible for 151 manatee deaths.[43] The bloom was present from early March to the end of April and killed approximately 15% of the known population of manatees along South Florida's western coast.[44] Other blooms in 1982 and 2005 resulted in 37 and 44 deaths, respectively.[45]

Additional threats

Manatees can also be crushed and isolated in water control structures (navigation locks, floodgates, etc.) and are occasionally killed by entanglement in fishing gear, such as crab pot float lines, box traps, and shark nets.[34]

While humans are allowed to swim with manatees in one area of Florida,[46] there have been numerous charges of people harassing and disturbing the manatees.[47] According to the United States Fish and Wildlife Service, approximately 99 manatee deaths each year are related to human activities.[48] In January 2016, there were 43 manatee deaths in Florida alone.[49]


All three species of manatee are listed by the World Conservation Union as vulnerable to extinction.

It is illegal under federal and Florida law to injure or harm a manatee. They are classified as "endangered" by both the state and the federal governments.

The MV Freedom Star and MV Liberty Star, ships used by NASA to tow space shuttle solid rocket boosters back to Kennedy Space Center, were propelled only by water jets to protect the endangered manatee population that inhabits regions of the Banana River where the ships are based.

Brazil outlawed hunting in 1973 in an effort to preserve the species. Deaths by boat strikes are still common.

In January 2016, the U.S. Fish and Wildlife Service proposed that the West Indian manatee be reclassified from an "endangered" status to "threatened" as improvements to habitat conditions, population growth and reductions of threats have all increased. The proposal will not affect current federal protections.[29]

As of February 2016, 6,250 manatees were reported swimming in Florida's springs.[50]

Manatees were traditionally hunted by indigenous Caribbean people. When Christopher Columbus arrived in the region, hunting was already an established trade, although this is less common today.[51]

The primary hunting method was for the hunter to approach in a dugout canoe, offering bait to attract it close enough to temporarily stun it with a blow near the head from an oar-like pole. Many times the creature would flip over, leaving it vulnerable to further attacks.

From manatee hides, Native Americans made war shields, canoes, and shoes, though manatees were predominantly hunted for their abundant meat.

Later, manatees were hunted for their bones, which were used to make "special potions". Until the 1800s, museums paid as much as $100 for bones or hides. Though hunting was banned in 1893, poaching continues today.

The oldest manatee in captivity was Snooty,[52] at the South Florida Museum's Parker Manatee Aquarium in Bradenton, Florida. Born at the Miami Aquarium and Tackle Company on July 21, 1948, Snooty was one of the first recorded captive manatee births. Raised entirely in captivity, Snooty was never to be released into the wild. As such he was the only manatee at the aquarium, and one of only a few captive manatees in the United States that was allowed to interact with human handlers. That made him uniquely suitable for manatee research and education.[53]

Snooty died suddenly two days after his 69th birthday, July 23, 2017, when he was found in an underwater area only used to access plumbing for the exhibit life support system. The South Florida Museum's initial press release stated, “Early indications are that an access panel door that is normally bolted shut had somehow been knocked loose and that Snooty was able to swim in.”[54]

There are a number of manatee rehabilitation centers in the United States. These include three government-run critical care facilities in Florida at Lowry Park Zoo, Miami Seaquarium, and SeaWorld Orlando. After initial treatment at these facilities, the manatees are transferred to rehabilitation facilities before release. These include the Cincinnati Zoo and Botanical Garden, Columbus Zoo and Aquarium, Epcot's The Seas, South Florida Museum, and Homosassa Springs Wildlife State Park.[55]

The Columbus Zoo was a founding member of the Manatee Rehabilitation Partnership in 2001. Since 1999, the zoo's Manatee Bay facility has helped rehabilitate 20 manatees.[56] The Cincinnati Zoo has rehabilitated and released more than a dozen manatees since 1999.[57]

Manatees can also be viewed in a number of European zoos, such as the Tierpark Berlin, the Nuremberg Zoo, in ZooParc de Beauval in France and in the Aquarium of Genoa in Italy. The River Safari at Singapore features seven of them.[58] They are also included in the plans of the Wild Place Project in Bristol, England, whose first exhibit is opened in summer 2013[59] with the manatees as an addition as early as 2015.[60]


The manatee has been linked to folklore on mermaids. Native Americans ground the bones to treat asthma and earache. In West African folklore, they were considered sacred and thought to have been once human. Killing one was taboo and required penance.[61]

In the novel Moby-Dick, Herman Melville distinguishes manatees ("Lamatins") from small whales; stating, "I am aware that down to the present time, the fish styled Lamatins and Dugongs (Pig-fish and Sow-fish of the Coffins of Nantucket) are included by many naturalists among the whales. But as these pig-fish are a noisy, contemptible set, mostly lurking in the mouths of rivers, and feeding on wet hay, and especially as they do not spout, I deny their credentials as whales; and have presented them with their passports to quit the Kingdom of Cetology."[62]

Manatees were featured in the "Cartoon Wars Part II" episode of South Park, as the creative force behind the television show Family Guy. The manatees were shown to be living in a tank at Fox Studios which was filled with "idea balls." The manatees randomly selected the idea balls to make the jokes for the show. They are also revealed as being "the only animal unmoved by terrorist threats."[63] The manatee is also pivotal in Lair of the Leviathan, the third episode of the game Tales of Monkey Island, by Telltale Games and Lucasarts.[64]
