Mating and HatchingAlmost all frogs fertilize the eggs outside of the female’s body. The male holds the female around the waist in a mating hug called amplexus. He fertilizes the eggs as the female lays them. Amplexus can last hours or days. One pair of Andean toads stayed in amplexus for four months.The marsupial frog keeps her eggs in a pouch like a kangaroo. When the eggs hatch into tadpoles, she opens the pouch with her toes and spills them into the water.Pipa pipa, the Suriname toad of South America (an enlarged model of a female with froglets is featured in the Museum’s Hall of Reptiles and Amphibians), carries her young embedded in the skin of her back. After mating, the eggs sink gradually into the female’s back, and a skin pad forms over the eggs. The developing juvenile frogs are visible inside their pockets for several days before hatching. They emerge over a period of days, thrusting their head and forelegs out first, then struggling free.he gastric brooding frog of Australia swallows her fertilized eggs. The tadpoles remain in her stomach for up to eight weeks, finally hopping out of her mouth as little frogs. During the brooding period, gastric secretions cease—otherwise she would digest her own offspring.Among Darwin frogs, it is the male who swallows and stores the developing tadpoles in his vocal sac until juvenile frogs emerge.Read more about

Frogs are tail-less amphibians (class Amphibia, order Anura). With some 3,500 living species, frogs are the most numerous and best known of amphibians. They are found on all continents except Antarctica and are common on many oceanic islands. The terms “frog” and “toad” are derived from early usage in England and northern Europe, where two families of the order Anura occur. One includes slender, long-legged, smooth-skinned animals that live near water: frogs; the other includes short-legged warty animals that live in fields and gardens: toads. When other kinds of animals of this group were discovered elsewhere, such as tree-frogs, fire-bellied toads, and others, it was realized that these various forms actually represented one major group. This group, the anurans, is now commonly referred to as frogs.Frogs are amphibians, a term derived from two Greek words: amphi meaning double and bios meaning life. The double life of frogs involves living in water and also on land. Because of this amphibious habit, they must have adaptations for each environment. As in other animals that have a separate larval stage and a complex life cycle, frogs have two extremely different morphologies.Tadpoles, the larval stage of frogs, are adapted to a purely aquatic life. They are seemingly reduced to the essentials, which in this case includes a globular body with a muscular, finned tail. Typically, tadpoles have no bones but rather a simple cartilaginous skull and skeleton. They also have no true teeth, instead having rows of denticles and a beak of keratin (a fingernail-like substance). The globular body is mainly filled with a long, highly coiled intestine.
