Description

The sailfin pleco is a large suckermouth catfish from fresh water of the Orinoco and Amazon basins of South America. The species grows to about 50 cm and has an elongate body covered with bony plates and a spotted pattern, a large sail-like dorsal fin and a fleshy sucker mouth. As a bottom-dweller it clings to stones and wood in rivers and grazes algae, aufwuchs and detritus; it can breathe air with its gut. In some areas outside its native range it is invasive. The IUCN has not evaluated the species.
