About Pleurodema diplolister (Peters, 1870)
Pleurodema diplolister, commonly called Peters' four-eyed frog, is a species of frog that belongs to the family Leptodactylidae. This species is endemic to Brazil. Its natural habitats include dry savanna, moist savanna, subtropical or tropical dry shrubland, subtropical or tropical dry lowland grassland, intermittent freshwater marshes, sandy shores, and pastureland. This species is currently threatened by habitat loss. The common name "four-eyed frog" comes from two inguinal poison glands that have an eye-like appearance. When the frog feels threatened, it lowers its head and raises its rear. This posture lifts the poison glands toward the predator. Additionally, a predator may mistake the frog's raised posterior for the head of a larger animal.
