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 a egg hatched to a tadpole, the tadpoles were counted as well.
