Some frogs lay their eggs on land, then transport tadpoles to the water, stuck on their backs. After fertilizing eggs, the male of the European midwife toad pushes his legs into the string of eggs until they are wound around his waist and legs. He carries the eggs with him on land until they are ready to hatch, at which point he returns to the pond. The hatched tadpoles are carried in the pouch until, at a later stage of their development, mother moves to a pond where the tadpoles emerge and keep growing. Still other frogs have their young developing within the egg membrane, emerging from a leafy nest as tiny froglets.
Tadpoles develop in the nest, into which water seeps.
This fascinating variation is an amazing display of the Creator's ingenuity, and the richness of the original genetic program of their kinds. Return to text Ref 1. Return to text Ref. Frogs are a favorite subject for biology classes, regularly going under the scalpel to help high school and college students understand anatomy. 1 People in various parts of the world, particularly France and Indonesia, eat frogs' legs as a delectable morsel.
