The Dusky tripletooth goby (Tridentiger obscurus) is a brackish-water fish of the family Gobiidae that grows up to 14 cm.
Description
The dusky tripletooth goby is a stocky goby of the family Gobiidae reaching about 14 cm. The brownish body bears dark cross-bars and rows of pale spots; the name refers to its conspicuous three-pointed teeth. Like other gobies the pelvic fins are fused into a sucking disc, with which the fish clings to stones. The species comes from East Asia and lives in brackish and fresh coastal and estuarine water around Japan, Korea and China, on stone and rock bottoms of tidal zones, where it tolerates strongly varying salinity. As an omnivore it grazes algae and seeks small crustaceans, worms and molluscs. Through ballast water and shipping it has locally turned up outside its range.
