About this species
Cosmocampus banneri is a species of marine fish of the family Syngnathidae. It is found from the Red Sea and Western Indian Ocean to Fiji, the Marshall Islands, and the Ryukyu Islands. It lives in coral reefs at depths of 2-30m, where it can grow to lengths of 5.8 cm. Although little is known about the feeding habits of C. banneri, it is expected to feed on small crustaceans similar to other pipefish. This species is ovoviviparous, with males carrying eggs in a brood pouch until giving birth to live young.
