Exotic invasive giant apple snails (Pomacea maculata) will depredate eggs of frog and toad species of the Southeastern United States.

Frog eggs of three different species were presented to giant apple snails (Pomacea maculata) to determine if the snails will eat the eggs. There were four treatments: control- eggs in water only; control with lettuce- eggs in water and lettuce which was used as snail food; snail- eggs in water with snail; and snail with lettuce- eggs in water with snails and lettuce (as an alternative food for the snail). Eggs were counted at the start and end of the experiment, and if an egg hatched to a tadpole, the tadpoles were counted as un-eaten eggs.
