Is a manatee related to a cow?
Actually, it is believed that manatees evolved from land animals. However, they are more closely related to elephants than they are cows.
How closely are manatees and elephants related?
The closest living relatives of sirenians are elephants. Manatees evolved from the same land animals as elephants over 50 million years ago and the fossil record shows a much more diverse group of sirenians than we have today, with dugongs and manatees living together throughout their range.
What animal is the queen of the sea?
Dugongs have also played a role in legends in Kenya, and the animal is known there as the "Queen of the Sea". Body parts are used as food, medicine, and decorations. In the Gulf states, dugongs served not only as a source of food, but their tusks were used as sword handles.
Are manatees related to hippos?
Hippos are members of the order Artiodactyla, which actually makes them more closely related to whales than manatees. Manatees are part of the order Sirenia, unique to fully aquatic herbivores, but scientists believe they actually share a common ancestor with elephants.
Is a manatee a dinosaur?
Manatees are aquatic mammals that belong to a group of animals called Sirenia.
Is a manatee related to a whale?

Do alligators eat manatees?
No, they don't. Actually, while alligators may bite the satellite tags attached to manatees and occasionally prey on manatee calves, they don't ordinarily bother manatees. Attacks by alligators are very rare, and boat strikes still remain the prime cause of death among adult manatees.
What eats a manatee?
Manatees don't really have any real predators. Sharks or killer whales or alligators or crocodiles could eat them, but since they don't usually inhabit the same waters, this is pretty rare. Their biggest threat is from humans. And because of this, all manatee species are endangered and threatened.
Do sharks eat manatees?
Although sharks can eat manatees, they do not often hunt actively for large bony animals such as manatees. A typical diet of a two-meter shark consists of fish that are less than one foot in length, making it difficult for them to deal with an animal as big as a manatee.

They constantly grow molars in the back corners of their mouth. As the front teeth grind down and eventually fall out, the molars fully emerge, pushing new teeth forward. Manatees are also anatomically incapable of using their teeth to attack.
How do manatees regulate buoyancy?
Manatees regulate their buoyancy with their lungs. Manatees’ lungs run along their spines on the top of their body. Their lungs are “like a flotation tank running along the backside of the animal,” Domning said. Using their rib cage muscles, they can compress their lung volume and make their bodies more dense.
How long do manatees eat?
Manatees spend six to eight hours a day eating sea grass and other aquatic vegetation. Their food has tiny granules of sand in it, which gradually wears down their teeth. Eventually, those teeth fall out.
What are some interesting facts about manatees?
8 things you didn’t know about manatees. Manatees are the slow, lumbering, gentle giants of the aquatic ecosystem. Every November, the West Indian manatee, native to the Gulf of Mexico and Caribbean Sea, makes its way to Florida’s warmer waters for the winter. The U.S.’s manatees are an endangered species floating close to extinction.

When did the Florida manatee rescue take place?
In 2009, Florida Fish and Wildlife Conservation Commission’s manatee rescue coordinator Andy Garrett airlifted a manatee from the Jersey Shore down to Florida’s warmer waters. With water temperatures dropping, the scientists worried that the manatee wouldn’t make it far enough south to survive.
How many fingernails does a manatee have?
Manatees have three or four fingernails, much like the toenails on an elephant’s feet. They both share a similar atypical heart structure. Elephants and manatees have a circular shaped heart.

2) The Only Vegetarian Marine Mammal. Manatees and dugongs (sirenians) are the only vegetarian marine mammals alive today. A manatee needs to eat 10-15% of its body weight each day. A manatee weighs 800-1200 lbs, therefore they need to eat roughly 100 lbs of sea grass and plants daily.
What is the function of manatees' upper lip?
Manatees have a large flexible upper lip which they use to guide vegetation into their mouths. The surface of this prehensile lip is covered with vibrissae (whiskers). Each whisker has its own separate follicular blood supply and nerve endings which help them feel their way through clumps of floating vegetation and root for nutrients in the seabed.
Is a manatee related to a dolphin?
Manatees are not related to dolphins or whales (cetaceans). On land, the elephant is their closest relative. Scientifically, manatees are classified as sub-ungulates and are descended from a common ancestor of the elephant. The other mammals in the Subungulata superorder are hyraxes and aardvarks.
What is the extinct family of meridiungulates?
The extinct meridiungulate family Archaeohyracidae, consisting of four genera of notoungulate mammals known from the Paleocene through the Oligocene of South America, is a group unrelated to the true hyraxes.
What are the descendants of the giant hyracoids?
The descendants of the giant "hyracoids" (common ancestors to the hyraxes, elephants, and sirenians) evolved in different ways. Some became smaller, and evolved to become the modern hyrax family. Others appear to have taken to the water (perhaps like the modern capybara ), ultimately giving rise to the elephant family and perhaps also the sirenians. DNA evidence supports this hypothesis, and the small modern hyraxes share numerous features with elephants, such as toenails, excellent hearing, sensitive pads on their feet, small tusks, good memory, higher brain functions compared with other similar mammals, and the shape of some of their bones.
What are some similarities between Hyrax and Sirenia?
Similarities with Proboscidea and Sirenia. Hyraxes share several unusual characteristics with mammalian orders Proboscidea (elephants and their extinct relatives) and Sirenia ( manatees and dugongs ), which have resulted in their all being placed in the taxon Paenungulata.
Overview
Taxonomy
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).
The Amazonian's hair color is brownish gray, and it has thick wrinkled skin, often with coarse hai…
Etymology
The etymology of the name is unclear, with connections having been made to Latin manus "hand" and to pre-Columbian Taíno manati "breast". The term sea cow is a reference to the species' slow, peaceful, herbivorous nature, reminiscent of that of bovines.
Description
Manatees weigh 400 to 550 kg (880 to 1,210 lb), and average 2.8 to 3.0 m (9 ft 2 in to 9 ft 10 in) in length, sometimes growing to 4.6 m (15 ft 1 in) and 1,775 kg (3,913 lb) and females tend to be larger and heavier than males. At birth, baby manatees weigh about 30 kg (66 lb) each. The female manatee has two teats, one under each flipper, a characteristic that was used to make early links between the manatee and elephants.
Behavior
Apart from mothers with their young, or males following a receptive female, manatees are generally solitary animals. 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 m (3 ft 3 in – 6 ft 7 in). The Florida subspecies (T. m. latirostris) has been known to live up to 60 years.
Ecology
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).
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 cann…
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, and disease.
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, disfigurem…
