Ounce for ounce, I don't know if there's anything in the animal kingdom as ravenously predatory as a frog. Many are the times I've sat on a high plains stock tank during the hot days of dove season watching as that year's crop of newly-emerged leopard frogs swam around the tank happily eating each other. And bullfrogs? Those beasts will, quite literally, eat anything they can fit in their mouths. And some things they can't. Don't believe me? Next time you see a bulfrog sitting on the moss, just toss a worm, a lizard, a rat, pretty much anything in your tacklebox near it and hang on.
