Description
The grass goby is a robust goby of the family Gobiidae reaching about 25 cm, one of the largest gobies of the Mediterranean region. The green-brown mottled body blends perfectly among seagrass; the head is broad and somewhat snake-like, to which the species name ophiocephalus refers. Like other gobies the pelvic fins are fused into a sucking disc. The species lives in seagrass beds of brackish coastal lagoons and shallow coastal water of the Mediterranean, the Black Sea and the Sea of Azov. Among the plants it hunts crustaceans, worms and small fish. In spring the male builds a nest among the seagrass roots and guards the eggs. Locally, especially in lagoons, it is a valued commercial and sport fish.
