Goblin Shark

The Goblin Shark is one of the strangest living sharks, sole living member of the ancient family Mitsukurinidae, a lineage stretching back over 100 million years. It inhabits deep continental slopes and submarine canyons worldwide, rarely seen by humans and known mostly from bycatch. Its soft, flabby, pinkish body results from thin translucent skin over blood vessels rather than true pigmentation. Adults typically reach 3-4 meters, with a maximum recorded size approaching 6 meters. The species is not commercially targeted and its deep habitat affords it protection, so it is currently assessed as of Least Concern conservation status despite limited population data.

• Long, flat, blade-like snout extending well beyond the mouth, longer than in any other living shark
• Jaws are highly protrusible, thrusting forward like a slingshot to seize prey, then retracting
• Slender, narrow, nail-shaped teeth adapted for gripping soft-bodied prey rather than cutting
• Pale pink to grayish-white flabby body from thin translucent skin over blood vessels
• Low-set small eyes, rounded pectoral and dorsal fins, long asymmetrical tail with a small lower lobe No other shark combines the extended flat snout with slingshot jaws and flabby pink coloration, making misidentification unlikely once the head is clearly visible.

Goblin Sharks occupy the outer continental shelf, slope, and submarine canyons at depths generally between 270 and 960 meters, though individuals have been recorded far deeper, over 1,300 meters. They favor cool, dark mesopelagic and bathyal waters worldwide, with records from Japan, the Gulf of Mexico, Taiwan, southern Africa, Australia, and France. Some evidence suggests they may move to shallower depths at night to feed. Because they live in such remote, high-pressure environments, live specimens are almost never observed, and most knowledge comes from individuals caught incidentally in deep-set longline and trawl fisheries.

Little is known of Goblin Shark behavior due to its deep, dark habitat, but it is believed to be a slow-moving, opportunistic ambush predator rather than an active pursuit hunter. Its flabby body and small fins suggest a low-energy lifestyle suited to a food-scarce deep environment, while its rapidly protrusible jaw allows it to strike prey with minimal body movement. Diet includes deep-sea fishes, squid, and crustaceans, detected using electroreceptive organs in the snout to locate prey in darkness. Reproduction is presumed ovoviviparous like related lamniform sharks, though litters have never been documented.
