Coleman's pygmy seahorse (Hippocampus colemani) is a species of fish of the family Syngnathidae. It is found off of the coast of Lord Howe Island, Australia, although unconfirmed occurrences have been reported from Milne Bay and the Ryukyu Islands.[1] It lives in coarse sand and Zostera and Halophila sea grasses at depths around 5m (16feet).[2] [1] It is expected to feed on small crustaceans, similar to other seahorses. Ovoviviparous reproduction is also expected, with males brooding eggs in a pouch before giving birth to live young.[1]
Named after Neville Coleman, an Australian diver and publisher of several popular books on diving and marine biology of the South Pacific area.[3]
Individuals of this species are tiny, growing to a maximum recorded length of 2.7cm (01.1inches).[2] They have small heads, short snouts, thick trunks, and low coronets. Algae that are found on seagrass blades attach to their skins, acting as a form of camouflage.[1] Colouration is generally pale whitish to yellowish, with white circular or elliptical markings outlined with narrow red lines on the trunk, dusky brown bands radiating from the eye, brownish-red appendages, and a slightly brownish tail with red markings.[4]
