These species are lesser-known and small members of the Istiophoridae family of billfish that are also referred to as slender spearfish. They are pelagic, offshore, deep-water fish that appear to be available all year in small numbers but are infrequently encountered by anglers in most parts of their range. They feed near the surface, mainly on small and medium-sized fishes and squids, including dolphin, sauries, flying fish, needlefish and pilot fish.
