Descrição breve Morfologia | Morfometria

Espinhos dorsais (total): 0; Raios dorsais moles (total): 0; Espinhos anais 0; Raios anais moles: 0. A slim, graceful blue shark with a long, conical snout, large eyes, and curved triangular upper teeth with saw edges; pectorals long and narrow; no interdorsal ridge (Ref. 5578). Dark blue dorsally, bright blue on the sides, white ventrally (Ref. 5578). Tips of pectoral fins and anal fin dusky (Ref. 9997). The first case of diprosopus tetrophthalmus (cranofacial duplication) in a foetus of this species was reported from South Atlantic (Ref. 119190).

Biologia     Glossário (ex. epibenthic)

Oceanic, but may be found close inshore where the continental shelf is narrow (Ref. 6871, 58302). Usually found to at least 150 m (Ref. 26938). Maximum size from Ref. 128029. Reported from estuaries (Ref. 26340). Epipelagic, occasionally occurs in littoral areas (Ref. 58302). Feeds on fishes (herring, silver hake, white hake, red hake, cod, haddock, pollock, mackerel, butterfish, sea raven and flounders (Ref. 5951)), small sharks, squids, pelagic red crabs, cetacean carrion, occasional sea birds and garbage (Ref. 5578). Viviparous (Ref. 50449). Sexual dimorphism occurs in skin thickness of maturing and adult females (Ref. 49562). May travel considerable distances (one specimen tagged in New Zealand was recaptured 1,200 km off the coast of Chile) (Ref. 26346). Potentially dangerous to humans (Ref. 6871, 13513). Marketed fresh, dried or salted, and frozen; meat utilized for consumption, hides for leather and fins for soup (Ref. 9987). Sexually mature at 250 cm long and 4-5 years old. The female gives birth up to 80 young measuring 40 cm long, gestation lasts almost a year (Ref. 35388). Produces from 4 to 135 young a litter (Ref. 26938). Minimum depth from Ref. 125614.

Life cycle and mating behavior Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas

Distinct pairing with embrace (Ref. 205). Viviparous (Ref. 26281), placental (Ref. 50449); 4-63 young in a litter (Ref. 9997); 4-135 (usually 15-30) pups (Ref.58048), about 35-44 cm at birth. Gestation period ranges from 9 to 12 months (Ref. 244). Sexual dimorphism is evident in skin thickness of maturing and adult females (Ref. 49562). Females have thicker skin layer than males of the same size (Ref. 49562).
