Description
The marbled goby is a small, sandy-coloured goby of the family Gobiidae reaching about 8 cm. The translucent body bears a fine marbled pattern with a few dark saddle blotches on the back; like other gobies the pelvic fins are fused into a sucking disc. The species tolerates strongly varying salinity and lives mainly in brackish coastal lagoons and estuaries of the Mediterranean, the Black Sea and the adjacent eastern Atlantic, on sand and mud bottoms of shallow water. On the bottom it searches for small crustaceans and worms. Breeding males are darker and defend a territory; they guard the eggs laid under a shell or stone until they hatch. Because of its small size it has no fishery importance.
