Description

The olive flathead-goby is a goby of the family Gobiidae (gobies) reaching about 17 cm. The olive-brown, blotched body has a somewhat flattened head; the genus Glossogobius takes its name from its forked tongue. Like all true gobies the species has the pelvic fins fused into a sucker with which it clings to the bottom. It comes from East Asia and lives in brackish river mouths, estuaries and coastal water, where it tolerates strongly varying salinities. On the bottom it preys on small crustaceans, worms and small fish. The male guards the laid eggs. Locally it is caught as a small food fish and is a link in the estuarine food web.
