:Still though, is it known what Goliath frogs eat as adults? I've never heard of a herbivorous frog before-my understanding is that almost all frogs eat insects and spiders. And last but not least how would one describe their vocalizations?[I'd imagine the goliath frog has a very deep, loud voice:P]
Goliath frogs are mute. They have no vocal sac.
Adult goliath frogs eat insects, crustaceans, fish and amphibians (newts, salamanders, and smaller frogs, for example). Goliath tadpoles, however, are vegetarians, feeding exclusively on certain waterplants found only near waterfalls and rapids. I found this on the web DSC
