Find out how foam nest frogs build impressive frothy structures for their young
Chiromantis is a genus of frogs found in Southeast Asia and the sub-Saharan tropics of Africa. These frogs are known as the foamnest tree frogs because of the impressive frothy structures they create when rain signals the start of the breeding season. While the foam nests may appear simple in comparison to other feats of animal architecture, they have some peculiar properties, and, in the case of the grey foam-nest tree frog, are the work of many determined legs.
