What is the common name of the frog that carries its eggs in a pouch on its back?

The frog that carries its eggs in a pouch on its back is commonly called a marsupial frog.

Marsupial frogs are members of the family Hemiphractidae, especially the genus Gastrotheca. They are named for the female’s dorsal brood pouch, which is a specialized pocket on the back rather than a mammalian-style belly pouch. During breeding, eggs may be fertilized on the female’s back and then placed into the pouch, sometimes with assistance from the male.

Inside the pouch, the developing embryos remain in contact with vascularized tissue that helps supply oxygen. Depending on the species, the young may emerge as tadpoles or as miniature froglets after undergoing much of their development inside the pouch. This unusual form of parental care helps protect eggs from predators and changing conditions in exposed water.

Marsupial frogs occur mainly in Central and South America, particularly in mountainous Andean habitats. They are easy to confuse with tree frogs because many species live in vegetation, but “tree frog” describes habitat or a broader grouping, not this distinctive reproductive adaptation. Glass frogs and poison dart frogs lack the characteristic dorsal brood pouch.
