Cool Stuff The name milk frog refers to the poisonous, white, milky secretion that this species may secrete when threatened. Because of their large vocal sacs, the males of this frog species are able to make extremely loud calls. Once the female lays her eggs, the male will continue with his mating calls to attract another female. But, when the next female comes, he will not fertilize her eggs when she deposits them. Instead, they become food for his already hatched tadpoles to eat.
