Cosmocampus darrosanus (D’Arros pipefish or whiteface pipefish) is a species of marine fish of the family Syngnathidae. It is found in the Western Indian Ocean, Sri Lanka, Indonesia, Guam, and the Great Barrier Reef (Australia).[1] It lives in tidepools and coral reefs to depths of 3m (10feet), where it can grow to lengths of 7.4cm (02.9inches). This species is ovoviviparous, with males carrying eggs before giving birth to live young.[2]
The specific name is taken from the type locality of D'Arros Island in the Amirante Islands.[3]
