Ikan bertulang rawan (sharks and rays) > Carcharhiniformes (Ground sharks) > Sphyrnidae (Hammerhead, bonnethead, or scoophead sharks)
Etymology: Sphyrna: Probable misspelling of sphyra (Gr.), hammer, referring to their hammer-shaped heads (See ETYFish); zygaena: zygaina, ancient Greek name for hammerhead sharks, derived from zygon, yoke, alluding to yoke-like shape of cephalofoil (See ETYFish).

Biologi     Daftar kata (contoh epibenthic)

Occurs inshore and well offshore (Ref. 5578), over continental and insular shelves (Ref. 244). Coastal, pelagic, and semi-oceanic, but often bottom associated at 1-139 m (Ref. 58302). Migrates northward in summer; young often in large aggregations of hundreds of individuals (Ref. 13562). Prefers to feed on small sharks, skates and stingrays, but also preys on bony fishes, shrimps, crabs, barnacles and cephalopods (Ref. 244). Viviparous (Ref. 50449). Regarded as being dangerous to people, though only few can be tentatively attributed to this species due to its occurrence in temperate waters (Ref. 244). Reported to cause poisoning (Ref. 4690). Caught occasionally by shark and tuna longline fisheries (Ref.58048). Meat utilized fresh, dried-salted, and possibly smoked for human consumption; liver oil for vitamins, fins for soup, hide for leather, and carcasses for fishmeal (Ref. 244). Used in Chinese medicine (Ref. 12166). Become sexually mature when 250 to 300 cm long. The female gives birth to 30 - 40 young (Ref. 35388).

Viviparous, placental (Ref. 50449), with 20 to 50 young per litter (Ref. 6871)after a gestation period of 10-11 months (Ref.58048). Size at birth between 50-60 cm TL (Ref. 13562).
