Etymology: Sphyrna: Probable misspelling of sphyra (Gr.), hammer, referring to their hammer-shaped heads. (See ETYFish);  mokarran: Arabic vernacular for this shark, described from the Red Sea, possibly from mogharn, horned, referring to the shape of its head. (See ETYFish).

Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 0; колючие лучи анального плавника: 0. A very large hammerhead also with a notch at the center of the head (Ref. 5578). Front margin of head gently curved in juveniles, becoming nearly straight in adults, with slight median notch (Ref. 26938). 1st dorsal fin very high and curved; 2nd dorsal and pelvic fins high and with deeply concave rear margins. Light grey or grey-brown above, white below; fins without conspicuous markings (Ref. 5578).

биология     глоссарий (например epibenthic)

A coastal-pelagic, semi-oceanic shark, found close inshore and well offshore, over the continental shelves, island terraces, and in passes and lagoons (Ref. 244, 58302). Often bottom and reef associated at 1-80 m (Ref. 58302). Prefers to feed on stingrays and other batoids, groupers and sea catfishes, but also preys on other small bony fishes, crabs, squid, other sharks, rays, and lobsters (Ref. 244, 13562, 1602). A viviparous species, with 13-42 of about 56 to 70 cm young in a litter (Ref. 26938, 1602). Potentially dangerous to people (Ref. 13562) but only few, if any, of the attacks on people can be definitely attributed to it because of the apparent difficulty of distinguishing large hammerhead species involved in attacks (Ref. 244). Caught occasionally by target shark longline, demersal tangle net and tuna gillnet fisheries (Ref.58048). Meat utilized for human consumption (fresh, fresh-frozen, dried-salted, and smoked), liver oil for vitamins, fins for soup, hides for leather, and carcasses for fishmeal (Ref. 244). Its large fins, including the tail, sail-like first dorsal fin, are prized in the Oriental sharkfin trade (Ref. 47737).

Life cycle and mating behavior Maturities | размножение | Spawnings | Egg(s) | Fecundities | личинки

Viviparous with a yolk sac placenta and 13-42 young in a litter (Ref. 244); 6-42 pups after gestation period of ~11 months (Ref.58048). Size at birth between 50 to 70 cm TL (Ref.58048, Ref. 13562).
