Pipefish and NEEDLEFISH are both members of the Syngnathidae family, which includes seahorses. Pipefish are elongated fish with a long, thin body and a small mouth, while NEEDLEFISH have a slender body and a long, pointed snout. Both species are found in shallow coastal waters and estuaries, and they feed on small crustaceans and plankton. Seahorses, on the other hand, are characterized by their horse-like head and prehensile tail, and they inhabit shallow tropical and temperate waters. They feed mainly on small crustaceans and plankton.
