Gyrinocheilidae (sucker loach; subclass Actinopterygii, order Cypriniformes) A small family of tropical freshwater fish that have a slender body, large eyes, and a single dorsal fin placed slightly ahead of the pelvic fins. The mouth is placed almost in line with the flat belly. The thickly built ‘lips’ enable the fish to attach itself firmly to rocks, but normally they are used to scrape algae from the surface of the rock. There are about three species, occurring in southeast Asia.
