Rio Maranon Poison Frog Excidobates mysteriosus

The Rio Maranon Poison Frog lives by the Maranon River in northern Peru. It is tiny, with a head and body length of less than an inch long.

The species has a regular body colour of white spots (or very pale green) on chocolate brown (no two have the same pattern). It is related to its neighbour on the Rio Maranon, the Rio Santiago Poison Frog (Excidobates captivus), which has red and yellow spots on a black background.

This endangered frog has a high risk of becoming extinct in the wild.
