Yakushima

Stiphodon surrufus is a small stream-dwelling goby described from Leyte in the Philippines and also reported from Okinawa and Yakushima, Japan. Males are reddish in life and lack elongate spines in the first dorsal fin. It was possibly carried north by the Kuroshio Current, and is less abundant there than congeners such as S. percnopterygionus. Like other Stiphodon it is a specialised algal grazer with an amphidromous life cycle.
