More Info


Distribution

Widely but patchily distributed in the Atlantic, Western Indian and Pacific oceans, living near the bottom at 95–1300m.

Most goblin sharks have been captured near the bottom in outer continental shelf and upper slope waters.

It has been suggested that goblin sharks are mesopelagic. They have very watery flesh that aids buoyancy, and stomach contenats of some individuals have contained midwater squid, crustaceans and fishes.

Features

Vertebrae 122–124 (53–56 precaudal)

Teeth 48-52 (upper jaw); 42-55 (lower jaw)

Head length 16–25% of TL.

Distinctive sharks with a large, flabby body and an elongate, depressed, tapering blade-like tapering extending over the greatly protruding jaws; teeth long, slender, lanceolate teeth; eyes small; caudal fin with a weak ventral lobe and an elongate upper lobe; exposed gill filaments; small lobe-like similar­-sized dorsal fins; anal fin present; small and broad pectoral fins.

Size

To about 4 m.

Colour

Pale grey to greyish brown. Goblin sharks often appear to pinkish-grey, however this is due to damage during capture.

Feeding

Carnivore. Goblin sharks have long slender grasping teeth and feed on fishes and invertebrates such as crustaceans and squids. The stomach contents of 121 Goblin sharks caught in the Tokyo Submarine Canyon contained bony fishes, squids and crustaceans (Yano et al. 2003).

The stomach of a juvenile female taken captured in a deep-water gillnet in off New Zealand contained the remains of mesopelagic fishes, squid and crustaceans.

Biology

The biology is poorly known. Like all sharks and rays, the sexes are separate, and males use claspers, or modified pelvic fins, for internal fertilisation. Although pregnant females are unknown, it is assumed Goblin Sharks are aplacental viviparous and give birth to live young. The litter sizes are thought to be small, and the embryos are probably oviphagous - a method of embryonic nutrition where the developing embryo feeds on unfertilised eggs and other embryos within the uterus.

The smallest Goblin Shark known measured 88 cm. Males mature by 264cm, females by 335cm

Fisheries

Occasionally taken as bycatch in deep-water commercial fisheries - deep bottom-set gillnets, bottom longlines and trawl fisheries. Taken regularly in small numbers in bottom-set gill nets off Japan.

Most captures that have been reported are of juveniles, suggesting most adults either live in deeper waters than commercial fisheries, or occur in habitats that are not fished.

Conservation

IUCN Red List: Least Concern.

EPBC Act 1999: Not listed

Remarks

The large spade-like snout of the Goblin Shark is covered with pores. These are the openings of the ampullae of Lorenzini - a mucous-filled canal system on the snouts of sharks and rays with electric receptors used to detect prey. 

Similar Species

The Goblin Shark is the only species in the family Mitsukurinidae.

Etymology

Mitsukurina is named after Keigo Mitsukuri, a Japanese zoologist who studied at University College London during the 1860's. The species owstoni was named in honour of Alan Owston (1853-1915), an English collector, primarily of wildlife in Asia.
