The shore clingfish, Lepadogaster lepadogaster, is a clingfish of the family Gobiesocidae, found in the eastern Atlantic from Ireland and Britain, where it is more commonly known as the Cornish lumpsucker, and in the Mediterranean, between latitudes 46° N and 30° N. L. lepadogaster often inhabits underwater boulder fields consisting of smooth rocks and large pebbles. Its length is up to 65 mm. L. lepadogaster is also classified as a cryptobenthic fish. Cryptobenthic simply means that the fish is both behaviorally and visually cryptic. The term is also used mainly to describe adult fish of a certain size, roughly around 5cm in length.
