Atrato climbing catfish

Astroblepus rengifoi is a species of freshwater ray-finned fish belonging to the family Astroblepidae, the climbing catfishes. This catfish is found in South America where it is known only from its type locality, a small stream that is a tributary to the Atrato River, around 6 km (3.7 mi) upstream from the town of El Carmen de Atrato, in the Chocó region of western Colombia. This species attains a maximum standard length of 5 cm (2.0 in).
The specific name, rengifoi, honors the entomologist Santiago Rengifo Salcedo, for his "ceaseless work for the advancement of biological science in Colombia".
