Description

The cleft-lip goby is a goby (Gobiidae) from the fresh waters of West Africa. The species has a stocky body with an inferior, crenelated-lipped mouth and fused pelvic fins forming a sucking disc. It is amphidromous: the larvae wash out to sea and the young return to ascend the river, climbing rapids and even wet rock faces with their sucker. It inhabits fast-flowing, rocky river sections, where it scrapes algae and diatoms from stones with its lips. The species is harmless to humans.
