Metallic roughy

The metallic roughy (Hoplostethus metallicus) is a slimehead of the order Beryciformes. It is native to the Western Central Pacific along the eastern seaboard of Negros Island in the Philippines and other locations in the Sulu Sea. It has a deep-water range of 55 - 550 m. It is known from only 25 collected specimens, but members of this genus are known to frequently be "locally abundant," occurring in dense schools over seamounts.
