Description

The frillfin goby is a stocky goby of the family Gobiidae (gobies) reaching about 15 cm. The brown, marbled body can change colour and pattern quickly for camouflage; like all true gobies it has the pelvic fins fused into a sucker with which the fish clings in surf and current. The species lives in tide pools and rocky, shallow coastal and estuarine waters on both sides of the Atlantic and tolerates strongly varying salinities. On the bottom it preys on small crustaceans, worms and small fish. It is famous for its ability to jump from pool to pool at low tide by remembering the terrain seen at high tide. The male guards the eggs laid under a stone.
