The life cycle of a frog, from egg to adult.


The life cycle of a frog, from egg to adult. Photos show an egg mass, a single egg with developing embryo, a day-old tadpole with gills and yolk sac, tadpoles with legs, and an adult. All photos are of wood frogs (Rana sylvatica) except the legged tadpoles, which are gray tree frogs (Hyla versicolor).
