The fingernails on the manatee are homologous structures.
Explanation:
The manatee is an animal that lives in the water, but it is not an animal that is related to the fish, instead it is a mammal. When the term mammal is mentioned, people often think of terrestrial animals, but some of the mammals are not living in the water, and have lot of characteristics that are very similar to the other marine animals.
