Description
The dogface goby is an amphidromous goby (Gobiidae) from fast-flowing mountain streams of tropical islands in the Indo-West Pacific. The species grows to about 12 cm and has an elongate body with a blunt, dog-like head and an inferior sucker mouth; the fused pelvic fins form a second sucker. As a larva it washes to sea and later returns to climb waterfalls with both sucking organs. On the stones it rasps algae and biofilm. The fish is harmless to humans.
