Description

The torrent sucker is a sucker (family Catostomidae) of eastern North America. The species reaches about 18 cm and has an elongate body with an inferior, fleshy sucking mouth. It inhabits rocky riffles and runs of moderate to swift creeks and small rivers; young fish stay in rocky runs and pools. With its sucking mouth it scrapes algae and small invertebrates from stones. The species is harmless to humans and, because of its small size, of no fishery value. It is an indicator of clear, fast-flowing water.
