The other subspecies is the Florida manatee (Trichechus manatus latirostris) , which is also considered to be endangered.

另一个亚种是佛罗里达海牛（Trichechus manatus latirostris），它也被认为是濒危物种。

Brady also says that the things they learned about the Florida manatees can be useful when it comes to understanding and protecting the other, lesser-studied manatee groups around the world.

Brady 还说，她们从佛罗里达海牛学到的知识，有助于理解和保护全世界较少被研究的其它海牛种群。

The West Indian manatee, the Florida manatee is an example, is no longer considered an endangered species by the U.S. federal government.

西印度海牛，佛罗里达海牛就是一个例子，美国联邦政府不再将其视为濒危物种。
