Itapotihyla
This frog eats animals with bones on the outside, for example grasshoppers and crickets.  It sometimes eats animals with spines, for example other frogs like Physalaemus crombiei and Scinax argyreornatus, or even birds.  Scientists know because they found bones and feathers in the frogs' stomachs. Snakes, for example Chironius bicarinatus, a colubrid, eat this frog.
