Description

The Japanese rock-climbing goby is an amphidromous goby of the family Gobiidae from East Asia. The species grows to about 13 cm and has an elongate body with an inferior, sucker-like mouth and a belly sucker from the fused pelvic fins. It lives in fast-flowing streams: after hatching the larvae wash to sea and the juveniles later run back up the rivers, where with both suckers they can 'climb' up waterfalls and rapids against the current. With its rasping mouth it scrapes adhesive algae (aufwuchs) from the stones. The species is a local delicacy and is harmless to humans.
