The common seasnail (Liparis liparis) is a small marine fish of the seasnail family (Liparidae) in the order Scorpaeniformes, the scorpionfishes and flatheads. It is found in the northeastern Atlantic Ocean where it lives on the seabed.
The common seasnail is an unusual-looking fish with a large head and front part of the body and a laterally compressed posterior part of the body and large fringing fins. Its length is generally between 8 and 14 cm (3.1 and 5.5 in). The bony head has two pairs of nostrils on the snout. The pectoral fins are very large and unite beneath the body. The pelvic fins take the form of a large sucking disc located between the pectorals. The dorsal fin has 27 to 36 soft rays and both it and the anal fins overlap the caudal fin. The skin is slimy and lacks scales.
The common seasnail is native to the northeastern Atlantic Ocean as far east as the Barents Sea, Novaya Zemlya, Spitsbergen and Bear Island and as far south as the British Isles. It is also present in the Baltic Sea and North Sea and the waters around Iceland and the east coast of Greenland. Its maximum depth range is around 300 m (984 ft) and it lives near the seabed.
The common seasnail feeds on small crustaceans, such as shrimps, crabs and amphipods, and also polychaete worms and fish. It breeds in the winter in the southern part of its range and in spring in the northern part. The eggs are laid on the seabed and the larvae are pelagic, forming part of the plankton.
