Family: Billfishes; Oceanic, usually found in surface waters above the thermocline, often near shore close to land masses, islands and coral reefs. Feed on fishes, squids, cuttlefishes, octopods, large decapod crustaceans and mostly on small tunas when abundant (Ref. 9668). The flesh is of good quality; marketed refrigerated or frozen and prepared as sashimi in Japan (Ref. 9308). Also Ref. 9692.
Distribution: most tropical and subtropical waters. Premaxilla and nasal bonesproduced, forming a spear-like bill or rostrum with a rounded cross-section. Gill membranes not united to isthmus. Very narrow pelvic fins. Jaw teeth present. Two keels on each side of caudal peduncle in adults. Dorsal fin extending over much of body length; sometimes resembling a sail. Dorsal fin
can be depresssed into a groove.Lateral line persists in life. Vertebrae 24. Maximum length 4 m. Bill used for stunning preyfish. The morphological adaptations required for maintaining high brain and retinal temperatures are discussed in Brock et al. 1993 Science 260:210-214. Very popular as game fish.
The family Istiophoridae belongs to the ClassActinopterygii (ray-finned fishes) and the Order Perciformes. It contains 3 genera and 11 species. It may be found in Marine environments and is primarily Marine.Members of this family are not used in the aquarium trade.
Reproductively, most members of this family are nonguarders. The main mode of swimming of adultfish in this family is thunniform. Compared with other fish, the activity level of this family tends to be very active. Members of this family have been dated back to the Cretaceous period.Etymology of this family name: Greek, istion = sail + Greek, pherein = to carry
Indo-Pacific: tropical and subtropical waters, occasionally entering temperate waters. Stray individuals migrate
into the Atlantic Ocean by way of the Cape of Good Hope, but the existence of Atlantic breeding stocks is unlikely. Highly migratory species, Annex I of the 1982 Convention on the Law of the Sea[1].
