Description

The chameleon goby is a stocky estuarine goby of the family Gobiidae reaching about 11 cm. It owes its name to its ability to switch colour pattern quickly: depending on mood and surroundings it shows two dark lengthwise stripes or instead dark cross-bars. Like other gobies the pelvic fins are fused into a sucking disc. The species is native to East Asia and lives in brackish and salt coastal and estuarine water on stone and rock bottoms and among fouling growth. Through ballast water and shipping it has spread to harbours in North America, Australia and the Mediterranean and Black Sea, where it becomes locally established. On the bottom it hunts small crustaceans, worms and molluscs.
