79 Fun Facts About Manatees

Why do Florida manatees sometimes gather around a running garden hose at a dock?

To drink fresh water: manatees in salty bays seek it out at river mouths, culverts and hoses. Offering it is against Florida's rules, because animals that learn to linger at docks lose their wariness of boats.

Which agency gave two ships based near Cape Canaveral water-jet thrusters so they would not harm local manatees?

NASA's Freedom Star and Liberty Star, which towed spent space shuttle boosters home, got a water-jet thruster because their base was on the manatee-rich Banana River, where a spinning propeller is a hazard.

Wildlife biologists use which farmyard term for an adult male manatee?

A bull: the terms follow cattle, with females called cows and their young calves. Bulls leave once breeding is over and play no part in raising a calf, which stays with its mother alone for up to two years.

In South Park's 'Cartoon Wars', which animated sitcom is revealed to be written by a tank of manatees?

Family Guy's jokes, the episode claims, come from manatees nudging 'idea balls' marked with nouns, verbs and pop-culture references into a machine; take a single ball away and the whole tank refuses to work.

In Brazil a manatee is a 'peixe-boi', a Portuguese name that translates as what?

Ox-fish: 'peixe' is fish and 'boi' is ox, the same comparison with slow, grazing cattle that English makes. Brazilians use the name for the river species and for the coastal one, the peixe-boi-marinho.

In The Simpsons episode 'The Bonfire of the Manatees', who walks out on Homer and ends up rescuing the animals?

Marge leaves after Homer lets mobsters shoot a film in their house, then joins Caleb Thorn, a manatee-saving scientist voiced by Alec Baldwin, until Homer tracks her down to win her back.

How does a manatee replace cheek teeth worn down by gritty plants?

They move forward from the back like a conveyor belt: fresh molars erupt at the rear and creep along the jaw as worn ones drop out at the front, so a manatee never runs out of chewing surface in its lifetime.

Which of these land animals is the manatee's closest living relative?

Elephant: protein and DNA studies make elephants some of the manatee's nearest living kin, far closer than the whales and seals it looks like.

Where on a mother manatee's body are the teats from which her calf nurses?

Under her flippers, about where armpits would be: a calf suckles from one teat on each side and starts nibbling plants within weeks, though it stays at its mother's side for up to two years.

Which kind of sound do manatee mothers and calves use to keep in touch?

High-pitched squeaks, with chirps and squeals mixed in, keep a cow and her calf in contact; a calf starts calling at or soon after birth, and each learns to recognise the other's voice.

Why can water below about 68°F be deadly for an animal as bulky as a manatee?

It has little insulating fat and a very slow metabolism, so it cannot make heat fast enough; a long chill brings on 'cold stress syndrome', which can kill even a full-grown adult.

How does a manatee drive itself forward through the water?

Pumping its tail up and down, as a whale does, moves a manatee along, while the two flippers steer, hold food and even 'walk' the animal across the bottom.

A manatee's tail is a rounded paddle, but what shape is a dugong's?

Fluked, like a whale's, with a notch in the middle: the tail is the quickest way for an observer to tell a dugong from a manatee.

Unlike most mammals' lungs, a manatee's long, flat pair runs along which part of its body?

Its backbone: the lungs stretch a metre or more along the spine, each with its own half of a split diaphragm, so a manatee can adjust its buoyancy and stay level in the water.

What often grows on a slow-moving manatee's back, tinting its grey skin green or brown?

Algae grow on the backs and tails of these slow swimmers. Barnacles hitch a ride in salt water too, then drop away once the manatee moves into fresh water.

Which part of a manatee seals shut automatically each time it submerges?

Its nostrils sit on top of the snout, so a manatee can breathe by raising just the tip of its nose above the surface; they clamp shut as it sinks back for a dive that can last many minutes.

What do manatees mainly use the stiff whiskers on their snouts for?

Feeling for and gripping food: the bristles flare outward to find and grasp plants, and they are sensitive enough to tell fine textures apart by touch alone.

Apart from mothers with calves, how do manatees generally live?

Mostly solitary: manatees drift together and apart with no leaders or lasting bonds, though they gather loosely where food is plentiful, and several males will trail a single female for weeks.

As of 2025, what was the IUCN Red List status of all three manatee species?

Vulnerable sits one step below Endangered on the Red List; for all three species the pressure comes from people, through hunting, fishing nets and the loss of the waters manatees feed in.

Which body part does a manatee use to grip plants and tear them free?

Its prehensile upper lip is split into two pads that move independently to grip and tear plants; manatees also use the same lips for touching and greeting one another.

The West Indian manatee has two subspecies: the Florida manatee and which other?

Antillean manatee: it ranges from Mexico through the Caribbean to Brazil. The two subspecies look alike, so scientists tell them apart by skull measurements and by where they live.

Besides manatees, which animals are the only mammals without exactly seven neck vertebrae?

Sloths: two-toed sloths can have as few as five neck vertebrae and three-toed sloths eight or more, against the manatee's six. Even a giraffe has the standard seven.

The 2021 starvation crisis among Florida manatees centred on which east-coast waterway, where pollution had killed the seagrass?

Indian River Lagoon: algal blooms fed by fertiliser and septic runoff shaded out most of its seagrass, so manatees wintering there starved, and deaths statewide jumped to about 1,100 in 2021.

In Sierra Leone, West African manatees are treated as pests for raiding which farm crop?

Rice: in the rainy season the animals drift into flooded fields and graze the plants, and they tear fishing nets too, so farmers and fishermen sometimes kill them.

Which manatee often has a white or pink patch on its chest and no nails on its flippers?

Amazonian manatee: the smallest of the three species and the only one confined to fresh water, it follows the floods into the forest in the wet season and retreats to deep lakes in the dry.

What did Florida's Manatee Sanctuary Act of 1978 declare to be a refuge for the animals?

The whole state: the act declares Florida 'a refuge and sanctuary for the manatee', so harassing or harming one is against the law in any water in the state, not only inside a marked reserve.

Where does a female manatee give birth?

Underwater: manatees never leave the water at any stage of life. The newborn has to reach the surface for its first breath, and within about an hour it can swim on its own.

West Indian manatees are 'euryhaline', meaning they tolerate a wide range of what in the water around them?

Salinity: West Indian manatees pass freely between rivers, brackish estuaries and the open sea. Their Amazon cousin does not, spending its whole life in fresh water.

Manatees are the only known animals whose eyes have which feature?

Corneas laced with blood vessels are a sign of disease in other animals, since a healthy cornea is clear and bloodless; in manatees they may be a response to the fresh water they spend so much time in.

About how much does a typical adult manatee weigh?

1,000 pounds is typical for an adult about 10 feet long, and all of it is built on low-energy water plants, which is why a manatee spends six to eight hours of every day grazing.

A manatee's eye closes in a way most like which of these?

A camera aperture: muscles ringing the eye draw it shut in a circle rather than with a blink from above and below. A thin inner membrane can also slide across to shield the open eye as the animal swims.

After a 2021 seagrass die-off left Florida manatees starving, wildlife officials took the rare step of feeding them what?

Lettuce and other leafy greens, at least 600,000 pounds over two winters, were handed out by staff and volunteers; the feeding ended once seagrass began to recover and starvation deaths fell away.

Steller's sea cow, a giant manatee cousin found by a shipwrecked Russian expedition in 1741, lived in which sea?

Bering Sea: the sea cows lived only around the Commander Islands, where Vitus Bering's ship was wrecked. At up to about 30 feet long they dwarfed any manatee, and the stranded crew lived on their meat.

As of 2025, which Walt Disney World park housed rescued manatees in the aquarium of its Seas pavilion?

Epcot: The Seas with Nemo & Friends keeps rescued West Indian manatees in a tank of their own, and it is one of the Florida sites where injured animals recover before going back to the wild.

Whales and seals fall under NOAA, but which federal agency is responsible for protecting manatees?

Fish and Wildlife Service: the 1972 Marine Mammal Protection Act split the animals between two agencies, giving it manatees, dugongs, walruses and polar bears and leaving whales, seals and sea lions to NOAA.

In hearing and sight tests, manatees have learned tasks about as well as which other sea mammals?

Dolphins: in acoustic and visual trials manatees matched them at telling signals apart, and their memories are long; Snooty, a captive manatee, still knew the voices of keepers from years before.

About how much does a newborn manatee calf weigh?

65 pounds is about average, nearly ten times a human newborn. A calf that size takes around a year to carry, and its mother will not bear another for at least two years.

Despite the nickname 'sea cow', a manatee digests plants in its hindgut much as which land animal does?

Horse: like one, a manatee has a simple stomach and ferments its food further along, in an outsized hindgut. A cow, by contrast, does the job up front in a many-chambered stomach.

Manatee Springs State Park, near Chiefland, feeds which Florida river?

Suwannee: the spring's short run holds a steady 72°F all year, so when the river and the Gulf turn cold, manatees swim up to shelter in it and sometimes to calve.

The bones hidden inside a manatee's flipper are arranged most like which of these?

A human hand: five jointed, finger-like digits lie under the thick skin, which is why a manatee can use its flippers to steer, hold food, scratch and even embrace another manatee.

Besides Florida, where else under the U.S. flag do wild manatees live all year round?

Puerto Rico: its manatees belong to the Caribbean subspecies rather than Florida's, and the island has its own conservation centre that rescues and rehabilitates injured animals.

Snooty, the Guinness-certified oldest captive manatee when he died at 69, was born at an aquarium in which city?

Miami: he was born in 1948, one of the first manatees known to be born in captivity, and at 11 months moved to a museum on Florida's Gulf coast, where he greeted visitors for the rest of his life.

Florida's Save the Manatee Club was co-founded in 1981 by Governor Bob Graham and which singer-songwriter?

Jimmy Buffett co-founded the club with Governor Bob Graham in 1981; its Adopt-A-Manatee program funds research, rescue and legal advocacy.

Which explorer's journal describes three 'mermaids', not as beautiful as painted, that were probably manatees?

Christopher Columbus saw them off Hispaniola in 1493 and complained that their faces looked rather masculine, which fits a whiskered manatee far better than a siren.

Satellite-tagged manatee Chessie, named after Chesapeake Bay, swam north in the mid-1990s as far as which state?

Rhode Island: Chessie reached Point Judith, then the farthest north a manatee had been tracked, and kept coming back to the Chesapeake; biologists confirmed the same animal off Maryland's Calvert County in 2011.

In 2006 a manatee turned up in the Wolf River harbor of which Mississippi River city?

Memphis: the manatee had swum more than 700 river miles up the Mississippi from the Gulf of Mexico, far beyond its range, and was later found dead about 10 miles downriver.

Which president signed the Marine Mammal Protection Act of 1972, which still protects manatees today?

Richard Nixon signed it in October 1972 and the Endangered Species Act a year later, so the two federal laws that guard manatees both date from his presidency.

In 2017 U.S. officials moved the West Indian manatee off the endangered list and into which lower-risk category?

Threatened: federal wildlife officials pointed to a growing population, while Save the Manatee Club objected that record boat-strike deaths had been overlooked. The animal's federal protections did not change.

The word 'manatee' may come from the Carib word manaty, meaning what?

Breast is the usual gloss of the Carib word, which reached English through Spanish 'manatí'. The origin is not certain, though: early writers also tied the name to the Latin word 'manatus'.

'Lamantin', an older alternative name for the manatee, comes from which language?

French: 'lamantin' is still the everyday French word for the animal, and English writers once used it as an alternative name before the Spanish-derived 'manatee' won out.

The genus name Trichechus comes from a Greek root meaning what?

Hair: Trichechus joins the Greek 'thrix', hair, to 'echein', to have, so the genus is literally 'the one with hair', named for the bristles on a manatee's muzzle.

When the dry season traps them in deep lakes, Amazonian manatees are thought to survive for months without what?

Eating: big fat reserves and a very slow metabolism are thought to let them fast for up to seven months, until the rising river lets them back into the flooded forest to feed.

Besides caimans and sharks, which predator is known to take Amazonian manatees?

Jaguar: natural predators take few manatees, though, and illegal hunting by people for meat remains by far the biggest threat to the species.

Mixira, sold illegally in Amazon markets, is manatee meat preserved in what?

Its own fat: mixira is manatee meat cooked and then sealed in its own lard. It fetches a high price, which is what keeps hunters going despite the ban.

African manatees live far inland in Mali, in the delta and lakes of which great African river?

The Niger: manatees swim upriver in the rains as far as its inland delta in Mali, far from the sea, and those that linger can be stranded and starve when the river shrinks in the dry season.

Along with plants, West African manatees are known to eat which shellfish?

Clams and other molluscs turn up in their diet, along with fish taken from nets, most of all on the coast; river animals browse overhanging plants and estuary animals eat mangrove leaves.

African manatees have been killed in the turbines of the Akosombo Dam, on which river?

The Akosombo Dam impounds the Volta River in Ghana as Lake Volta; dams such as Akosombo and Diama have also cut manatee populations off from the coast, genetically isolating them.

Blooms of the alga Karenia brevis, which poison manatees, go by what colourful name?

Red tide: Karenia brevis lives almost only in the Gulf of Mexico, and its toxins reach manatees both in the air they breathe at the surface and on the seagrass they eat.

In which country did sugar estates use manatees to keep irrigation canals free of weeds?

Guyana's sugar estates put manatees to work grazing weeds out of irrigation canals, and Georgetown's water treatment plant did the same in its storage canals in the mid-20th century.

Wardell the manatee sells furniture in the Happy Home Paradise expansion to a game in which Nintendo series?

Animal Crossing: Wardell arrived in 2021 with Happy Home Paradise, a paid add-on to New Horizons, where he runs the furniture catalogue for the holiday homes that players design.

Which novel's narrator expels 'Lamatins' and dugongs from his 'Kingdom of Cetology'?

In Moby-Dick's 'Cetology' chapter Ishmael dismisses lamatins and dugongs as noisy river-mouth lurkers that feed on 'wet hay' and, crucially, do not spout.

Kipling's 'The White Seal', whose hero follows a herd of Sea Cows, is in which collection?

'The White Seal' appeared in The Jungle Book (1894); its hero Kotick follows the slow, silent Sea Cows to a beach that men have never found.

Snooty the manatee's name is popularly linked to Baby Snooks, the radio role of which comedian, later portrayed in Funny Girl?

Fanny Brice played the mischievous toddler Baby Snooks on radio until 1951. The calf was plain 'Baby' at first; 'Baby Snoots' came in late 1949 and wore down to Snooty as he grew.

Manatee County, created in 1855, has which city as its seat of government?

Bradenton: the county, named for the animal, once covered land that is now several counties, and the city's museum was home for decades to Snooty, the manatee the county made its official mascot.

Which Florida city is home to the only national wildlife refuge created specifically to protect manatees?

Crystal River: the refuge was set up in 1983 around the springs of Kings Bay, whose water holds at 72°F all year and draws hundreds of manatees in from the cold Gulf each winter.

Blue Spring, a state park near Orange City famous for its manatees, is the largest spring on which river?

St. Johns: the spring run stays warm when the river turns cold, so manatees crowd into it each winter, and all swimming and boating in the run stops until they leave.

At Homosassa Springs Wildlife State Park, visitors watch manatees from what structure?

A floating observatory, nicknamed the Fish Bowl, is moored over the main spring; visitors walk down inside it and watch manatees and fish through windows below the waterline.

At Apollo Beach on Tampa Bay, a viewing centre lets visitors watch wintering manatees gather in the warm outflow of what?

A power station: Tampa Electric's Big Bend plant has had a public viewing area since 1986. Outfalls like it let manatees winter farther north than they once did, which worries biologists as old plants close.

Steller's sea cow was wiped out within 27 years of its discovery by crews hunting which animal for its fur?

Sea otters drew Russian fur traders to the islands, and the slow, tame sea cows became their larder: one animal could feed a crew for weeks. The last is thought to have been killed in 1768.

Unlike seagrass-grazing manatees, the extinct Steller's sea cow fed mainly on what?

It fed on kelp: too buoyant to dive, it could only crop the canopy near the surface, tearing the fronds with stiff bristles on its lip, since it had no teeth at all.

Which small furry land mammal is, surprisingly, one of the manatee's closest living relatives?

Hyrax: a rotund, well-furred animal no bigger than a rabbit hardly looks the part, yet anatomy and protein studies place it right beside the sea cows on the mammal family tree.

Pezosiren, a 50-million-year-old early relative of the manatee dug up in Jamaica, had what that its modern kin lack?

Four legs: Pezosiren, nicknamed the 'walking manatee', is thought to have lived rather like a hippo, at home on land and in water, before its descendants gave up their hind limbs for good.

Manatee ribs are unusually dense, solid bone with little marrow, which mainly helps the animal do what?

Stay submerged: the heavy ribs, thickened by a process called pachyostosis, work as ballast against the lift of the air-filled lungs, so a manatee can hold itself on the bottom to graze.

Male dugongs, unlike manatees, grow a pair of tusks from which teeth?

Dugong tusks are the upper incisors, which erupt through the gum in males at puberty; females' incisors keep growing hidden and sometimes erupt in old age.

The dugong, the manatees' closest living cousin, has its largest population in the waters of which country?

Australia: dugongs favour wide, shallow, sheltered bays where seagrass grows, and they range along its northern coast in an arc from Shark Bay round to Moreton Bay.

Touch sensors scattered all over a manatee's body detect water movement much as which organ does in fish?

Lateral line: the fine bristles scattered over a manatee's body are all touch sensors, picking up currents and the pressure wake of anything moving nearby, which helps it find its way in murky water.

Florida manatees have strayed as far north as Dennis, a town on a famous New England cape in which state?

Massachusetts: Dennis is on Cape Cod, the far end of a summer wander up the Atlantic coast. Other Florida manatees turn west instead and reach Texas, but all must be back in warm water before winter.

Researchers tell individual Florida manatees apart mainly by photographing what?

Their scars: the pale marks last for decades and most adults carry them, some from ten or more separate hits, so scientists keep a photo catalogue that matches each pattern to one animal.

River Safari, renamed River Wonders in 2021, keeps a breeding group of manatees in which Asian city?

Singapore: the park's largest tank holds a group of West Indian manatees that has bred well, and in 2016 two young males from the group were sent to Guadeloupe for a reintroduction project.
