The Hawaiian blackhead triplefin (Enneapterygius atriceps), also known as the Hawaiian triplefin in Hawaii,[2] is a species of triplefin blenny in the genus Enneapterygius.[2] It is a tropical blenny found in coral reefs in the Pacific Ocean, from the Hawaiian Islands, French Frigate Shoals, Laysan Island, and Midway Atoll.[2] Blennies in this species swim at a depth range of 1–23 metres, and inhabit dead coral and rock.
