Orange Roughy (Hoplostethus atlanticus)

Also known as the Red Roughy, Slimehead or Deep sea Perch, the orange roughy is a deep sea species of slimehead (Trachichthyidae) that inhabits the bathypelagic zone in the Western Pacific, eastern Atlantic, Indo-Pacific, and Eastern Pacific oceans. Orange roughy are sluggish and generally feed near the bottom, feeding mainly on zooplankton like crustaceans, small fish and squid. Orange roughy are noted for their extraordinary lifespan, with individuals living up to 149 years old. They are slow-growing and late to mature, which might cause their long lifespan.
