The manatee refers to animals in the class Mammalia, order Sirenia, family Sirenidae, and genus Sirenia.At present, manatees are not extinct.There are three other living manatee species, called the "American manatee," the "Amazon manatee," and the "African manatee.".However, they are currently endangered species, the number has been relatively small, especially wild species.Human hunting is one of the important reasons for their decline until they are now endangered.Their decline is also related to their slow reproductive rate, a manatee generally breeds at most once a year, and generally can only give birth to one, and this small manatee may also die for various reasons.
Although not all manatees are extinct, there is one species that is extinct, the "Stella's manatee," also known as the "sea cow," and no such animal exists today.
The manatee is an aquatic mammal and needs to live in water.Specifically, most manatees live in seawater, which is why they get the name "manatee".Manatees have been diving into the estuary of the river distribution is more, in the deep sea area is rarely seen, they will not go to the deep sea area.In addition to manatees distributed in the ocean, a small number of them live in fresh water and can live in rivers on land.From the latitude of distribution, manatees are basically distributed in lower latitudes, because they have higher requirements for temperature, can not survive in cold water, generally speaking, at least 16 degrees above.
