Pipefish

Pipe-fish, a popular name for any fish of that group of the family Syngnathidge in which the tail generally has a caudal fin, but is not prehensile as it is in the Sea-horses. The jaws are tubular, and the body is greatly elongated. The males usually carry the eggs till they are hatched in a pouch or glued to the abdomen. The Great Pipe-fish (Syngnathus acus) is common on both sides of the Atlantic, and far from rare in rock-pools on our coasts. Three species of the allied genus Nerophis are also British. The name is sometimes given from its shape to the Tobacco-pipe fish (Fistularia tabaccaria), which belongs to a different order.
