Ololygon alcatraz  is one of two endangered amphibian species that occur on Alcatrazes Island. Despite being abundant on the island, the species is on the list of endangered animals alone.  exist  in that location.


In the open sea, rises from the depths a huge mountain range, whose summit is so high that it pierces the blue ocean, forming the beautiful island of Alcatrazes. There, in this small and distant piece of Atlantic Forest, animals and plants continued their evolutionary history in complete isolation from continental species. This made unique features emerge. Sometimes so different from their continental brethren that they are recognized as distinct species. This is the case with the frogs from Alcatrazes.
