Eupsophus

The genus Eupsophus is a group of frogs belonging to the family Leptodactylidae, primarily found in South and Central America. These frogs are known for their diverse reproductive strategies. Some species, like those in the genus Leptodactylus, lay eggs in a frothy mass on land, with the young developing in the foam until rain washes them into a pool.1

A notable characteristic of some Eupsophus species is the presence of brightly colored "eyespots" on their rump. When threatened, these frogs lower their heads and raise their hindquarters, presenting the predator with what appears to be a much larger head. This is a defense mechanism to startle or confuse potential predators.2
