Co-QUI! Co-QUI! This little fellow isn't shy at all, shouting his name out from dusk till dawn. And why should he be? Eleutherodactylus coqui is, after all, the official animal of Puerto Rico, where this small tree-dwelling frog primarily makes his home... and yes, it's the "him" who is the homemaker here! After the female lays the fertilized eggs, the male coqui frog shoos her away and then faithfully stands guard until the eggs hatch into froglets - unlike most frogs, coquis don't go through a tadpole stage but hatch out already in pretty much their adult form. Quite a distinctive frog, eh?
