Description

The sea stickleback is a very slender, elongate marine fish of the family Gasterosteidae reaching about 22 cm, the longest of the sticklebacks. The thread-like body has a long, pointed snout and bears fourteen to seventeen short, separate spines before the actual dorsal fin; the tail base is strikingly thin. The species lives among seagrass and weeds in shallow coastal water of the north-eastern Atlantic coast, the North Sea and the western Baltic. It hunts small crustaceans, fish larvae and zooplankton. Like the other sticklebacks the male builds a nest, here of weed strands glued together with a kidney secretion, and guards the eggs and young. Because of its small size it has no fishery importance.
