Description

Stimpson's goby is a goby endemic to the streams of Hawaii. The species grows to about 20 cm and has a stocky body with an inferior sucking mouth and a ventral sucking disc from the fused pelvic fins. Remarkably, after a marine larval phase the young enter the river mouths and can use mouth and disc to climb even high waterfalls to reach the upper reaches. With the sucking mouth it rasps algae and diatoms from stones. The fish is harmless to humans. The IUCN assesses the species as Least Concern (LC).
