If anyone visits Puerto Rico, I can guarantee that they will be able to listen to the call of the Coqui Frog. The most abundant species of amphibians in Puerto Rico are frogs from the genus Eleutherodactylus. There are 17 species, and they can only be found in the Island, but scientists believe that three species have already gone extinct.
