Dunckerocampus pessuliferus (yellowbanded pipefish), occasionally Doryrhamphus pessuliferus, is a species of marine fish of the family Syngnathidae. It is a coastal species, inhabiting waters around the Coral Triangle, including the Philippines, Indonesia, and northwestern Australia. It lives in coral patches on sandy and muddy slopes at depths of 15–44 metres (49–144 ft), where it can grow to lengths of 16 centimetres (6.3 in). It is an active cleaner, feeding off of parasitic crustaceans growing on other fishes. The adult fish form pairs and are normally observed swimming along the bottom around large remote coral heads on muddy slopes. This species is ovoviviparous, with males carrying eggs and giving birth to live young.
