Goblin Shark

Fascinating facts about the Goblin Shark

• A living fossil with a snout like a flattened sword: the goblin shark has barely changed in 125 million years, yet we didn't find one alive until 1898 — and it took another century before we saw it hunt. Its long, flat rostrum (snout) is studded with electroreceptive pores that detect the faintest electrical fields of prey in absolute darkness, turning it into a living metal detector prowling 200–1,200 metres below the surface.
• Its jaws don't work like other sharks'. A goblin shark's mouth sits at the tip of its snout, and its entire jaw apparatus can shoot forward up to 9 centimetres in less than a tenth of a second — a strike so quick prey have no escape route. Combined with needle-sharp teeth designed to snag slippery fish, this is a predator shaped by millions of years of deep-sea stealth.
• At full size, a goblin shark weighs barely 18 kilograms — about as heavy as a large dog — but stretches over 3 metres long. That's because its skeleton is cartilage, not bone, and its body is mostly water. In the crushing pressures of the deep ocean, this flimsy frame is actually an advantage: less muscle means less energy needed, a critical trade-off when food is scarce.
• The ocean kept its reproduction secret until 2007: female goblin sharks give birth to live pups, and pregnancy lasts around 12 months. We learned this from only a handful of dissected specimens in over a century — a reminder that the deep sea remains so unexplored we still discover basic life histories of creatures that have lived here since the age of dinosaurs.
• Its colour betrays a lifestyle of low energy: the goblin shark is pale pink, almost translucent, with zero pigmentation to speak of. Down here, there is no sunlight to warn off predators or attract prey with colour, so it abandoned the metabolic cost of skin pigmentation entirely. What looks ghostly to us is simply a shark optimised to waste nothing in a world where meals arrive months apart.

About the Goblin Shark

In the dark, mysterious depths of the ocean, the goblin shark glides with an otherworldly elegance, its pinkish-brown body undulating as it navigates the desolate seafloor. With a flabby, elongated snout and jaws lined with tiny, needle-like teeth, this ancient creature is a master of the dimly lit abyss, its electroreceptive organs guiding it through the darkness in search of unsuspecting prey. As it moves, its soft, flaccid body seems to absorb the faint glow of bioluminescent creatures, rendering it all but invisible in the blackness.
