Description

The lesser pipefish is a very thin, long marine fish of the family Syngnathidae, related to the seahorses, reaching about 18 cm. The snake-like body is encased in bony rings and tapers in front into a short, tubular snout with a small mouth, with which the fish sucks in small plankton. It resembles the larger greater pipefish but is smaller, more slender and has a shorter snout. The species lives in shallow coastal waters, estuaries and tidal areas of the North Sea and the north-eastern Atlantic coast, often among seagrass and weeds. Like other pipefishes the male carries the fertilised eggs in a brood pouch under the tail and 'gives birth' to the young. Because of its small size it has no fishery importance.
