我们所说的海牛指的是生物学分类中海牛目的动物。这个大家族中共有五种海牛,分别是:1.西印度海牛;2.西非海牛;3.亚马孙海牛;4.儒艮(gèn);5.斯特拉大海牛。西印度海牛——西印度海牛是最常见的一种海牛,生活在美国东南部的沿海水域和内陆水道里,大部分集中在佛罗里达州。佛罗里达州甚至将海牛定为该州的州海洋哺乳动物。在墨西哥东海岸、美洲中部和南部地区也能找到西印度海牛。西印度海牛现存数量仅有3000头左右,这意味着它们也面临着灭绝的危险。
The manatees we refer to are the animals of the order of the sea cow in the biological classification. There are five kinds of manatees in this large family, namely: 1. West Indian manatee; 2. West African manatee; 3. Amazonian sea cow; 4. Dugong (gèn); West Indian Manatee - West Indian manatees are the most common type of manatee, living in coastal waters and inland waterways in the southeastern United States, mostly in Florida. Florida has even named the cow as the state’s marine mammal. West Indian cattle can also be found on the eastern coast of Mexico, in the central and southern Americas. The extant number of West Indian manatees is only about 3,000, which means they are also at risk of extinction.
