Urocampus carinirostris, also known as the hairy pipefish, is a species of marine fish belonging to the family Syngnathidae.

[1] They can be found inhabiting shallow seagrass beds and estuaries in Papua New Guinea and along the southern coast of Australia from Queensland to Swan River, Western Australia.

[2][3] Urocampus carinirostris is an ambush predator that is most commonly found on the edges of protected seagrass beds and near mangrove.

[4][5] Its diet consists of copepods and other small crustaceans.

[4] Reproduction occurs through ovoviviparity in which males brood around 48 eggs in a pouch beneath their tail before giving live birth to fully formed offspring.
