Peckoltia capitulata

Peckoltia capitulata is a species of catfish in the family Loricariidae. It is native to South America and occurs in the Approuague River in French Guiana. The species was initially collected from a part of the river with a swift, strong current, which was unusually turbid at the time due to illegal gold mining activities in the area.
The species reaches a size of 7.6 cm standard length. Its specific epithet, capitulata, is derived from Latin and refers to the species characteristically small head.
