Description

The greater pipefish is a strikingly long, thin marine fish of the family Syngnathidae, related to the seahorses, reaching about 50 cm. The snake-like body is encased in bony rings and tapers in front into a long, tubular snout with a small mouth, with which the fish sucks in small plankton. The species lives among seagrass and weeds of the eastern Atlantic, the North Sea and the Mediterranean, often in shallow, sheltered water. Most remarkable is its reproduction: the female lays the eggs in a brood pouch under the male's tail, which he incubates and from which he 'gives birth' to the young. Because of its small size it has no fishery importance.
