Pleurodema bibroni

Its common name is four-eyed frog,[2] although this name can also refer to the genus Pleurodema in general.

[3] The common name refers to two inguinal poison glands that resemble eyes.

The predator may also confuse the frog's raised posterior for the head of a larger animal.

It is threatened by habitat loss caused by encroaching agriculture, human settlements, and pine plantations.

[1] It is suspected that the urbanization of some coastal areas is responsible in part for the decline of the species.
