Carcharhiniformes (Ground sharks) >
Carcharhinidae (Requiem sharks)
Etymology: Carcharhinus: karcharos (Gr.), sharp or jagged; rhinus, an ancient name for sharks, from rhine (Gr.), rasp, both words alluding to a shark's jagged, rasp-like skin. (See ETYFish); obscurus: Latin for dark, probably referring to its darkish blue-gray body color. (See ETYFish).

ການຖ່າຍທອດທາງກຳມະພັນຈາກພໍ່ແມ່ຫາລູກ 0; ຄີກົ້ນຂອງປາ: 0. A large shark with a broadly rounded snout, triangular saw-edged upper teeth, curved moderate-sized pectoral fins, and an interdorsal ridge (Ref. 5578). Blue-grey, lead-grey above, white below; tips of pectoral and pelvic fins, as well as lower lobe of caudal fin and dorsal fins often dusky in young, plain in adults (Ref. 9997).
Found in coastal and offshore waters but not oceanic (Ref. 5578). Adults are commonly found at depths of 200-400 m, young in shallower waters (Ref. 5485). A seasonal migratory species over parts of its range (Ref. 6871). Common component of the catch of the shark longline fishery (Ref.58048). Feeds on bottom and pelagic bony fish, sharks, skates, rays, cephalopods, gastropods, crustaceans, sometimes mammalian carrion and inorganic objects (Ref. 5578). Viviparous (Ref. 50449); with litter size number from 3-14 (Ref. 27549). Large adults are potentially dangerous (Ref. 4716, 6871). Utilized fresh, dried-salted, frozen and smoked for human consumption; hides for leather; fins for sharks-fin soup; and liver oil extracted for vitamins (Ref. 244).
Viviparous, with a yolk-sac placenta, litter size 3-14 pups (Ref. 244); 70-100 cm at birth (Ref. 6871). Gestation period of ~ 16 months (Ref.58048). Distinct pairing with embrace (Ref. 205).
