Mitsukurinidae (Goblin shark)
Etymology: Mitsukurina: -ina (L.), belonging to: University of Tokyo zoologist Kakichi Mitsukuri (1858-1909), who placed holotype (provided by Alan Owson, see species) of this “very remarkable shark” in Jordan’s “hands to be identified, figured, and described”. (See ETYFish); owstoni: In honor of Alan Owston (1853-1915), English businessman, yachtsman, collector of Asian wildlife, and resident of Yokohama, Japan, who secured holotype from a fisherman (named for Owston at the request of Kakichi Mitsukuri, see genus). (See ETYFish).

marin bathydémersal; profondeur 30 - 1300 m (Ref. 43278), usually 270 - 960 m (Ref. 43278). Deep-water; 48°N - 55°S, 180°W - 180°E

Western Indian Ocean: off South Africa. Western Pacific: Japan, Australia (South Australia, New South Wales), New Zealand (Ref. 26346). Eastern Pacific: USA (southern California) (Ref. 43278).
Length at first maturity / Taille / Poids / Âge
Maturity: Lm 293.0, range 264 - 322 cm
Max length : 617 cm TL mâle / non sexé; (Ref. 83323); common length : 200 cm TL mâle / non sexé; (Ref. 5217)
Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 0; Épines anales 0; Rayons mous anaux: 0. Flat, bladelike, elongated snout, tiny eyes without nictitating eyelids, soft, flabby body, slender, very long cusped teeth in long, protrusible jaws, long caudal fin without a ventral lobe (Ref. 247). Pinkish-white with bluish fins, becoming brownish grey after death (Ref. 5578, 11228).
Found on outer continental shelves and upper slopes, but rarely in shallow water close inshore (Ref. 247, 43278). Jaws are highly specialized for rapid projection from the head to snap up small animals (Ref. 247). Feeds on jacopever, pelagic octopus and crabs (Ref. 5578). Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother (Ref. 50449). Probably slow-moving and neutrally buoyant (Ref. 6871). Utilized dried salted (Ref. 247)
Life cycle and mating behavior
Maturité | Reproduction | Frai | Œufs | Fécondité | Larves
Exhibit ovoviparity (aplacental viviparity), with embryos feeding on other ova produced by the mother (oophagy) after the yolk sac is absorbed (Ref. 247, 50449). Distinct pairing with embrace (Ref. 205).
