The Yellow-Banded Pipefish (Dunckerocampus pessuliferus) is a small marine (saltwater) fish in the Syngnathidae family of seahorses, pipefish, and seadragons. 

The Yellow-Banded Pipefish looks like a thin, straight seahorse or a small sea snake. It is a long, tube-like, cyclindrical fish with a small mouth. It has alternating reddish-brown and yellow bands along its body. Its snout (nose) is a long tube ending in a narrow mouth which opens upwards and is toothless. It has a dorsal (back) fin, which is always moving because it helps the Pipefish to swim. It has small gill openings, called slits, which enable it to breathe underwater. It has a paddle-shaped tail.
