Description

The milkyfin goby is a small, sandy-coloured goby of the family Gobiidae reaching about 9 cm. The brownish body bears faint spots, and the fins are milky-white to yellowish, from which the species takes its name; like other gobies the pelvic fins are fused into a sucking disc. The species comes from East Asia and lives in brackish and fresh coastal and estuarine water around Japan, Korea and China, on sand and mud bottoms of tidal zones, where it tolerates strongly varying salinity. On the bottom it searches for small crustaceans, worms and detritus. The male guards the eggs laid under a shell or stone until they hatch. Because of its small size it has no fishery importance.
