Description

The bigmouth pleco is a South American armoured catfish of the family Loricariidae from the Guianas. The species grows to about 14 cm and has a flattened, dark body armoured with rows of bony plates, and a downward-facing suckermouth. It is the most common and abundant species of its genus and inhabits rivers and rapids. With its rasping suckermouth it scrapes algae, growth and detritus from stones and wood. Loricariids cling to the substrate with the suckermouth in flowing water. The species is harmless to humans.
