In the 1970s, when Peter Benchley and Steven Spielberg conceived the idea for Jaws and the terrifying shark that has become a symbol of our shared fears, they envisioned a giant white shark enhanced by steroids. The shark in question, as estimated by Quint (Robert Shaw), was 25-feet long, which is about 5-feet longer than the largest known real-world white sharks.
The main takeaway from Jaws, marking its 50th anniversary, is that there exist terrifying creatures lurking in the depths, large enough to consume you entirely. Typically, when we envision sharks, it’s the menacing great white shark that comes to mind. However, it’s crucial to remember that not all sharks are gigantic. In fact, some of them are incredibly small, like the peculiar dwarf lanternshark (Etmopterus perryi), recognized as the smallest known shark on Earth.

Sharks possess not just sight, hearing, taste, touch, and smell, but also three extraordinary senses that set them apart. Researchers are exploring these unique abilities, particularly in Great Whites. Let me introduce you to “Contender,” believed to be the biggest male Great White Shark in the North Atlantic.
The smallest shark in the world, the dwarf lanternshark, is a glowing mini-Jaws
The dwarf lanternshark was found several decades back by a research vessel belonging to the U.S. Fish and Wildlife Service named Oregon. This discovery, along with another species of lanternshark, was reported in the 1985 edition of the journal Copeia. The dwarf lanternsharks are the tiniest members of a larger family of lanternsharks, all of which are relatively small. The largest species within this family, the great lanternshark (Etmopterus prineps), measures approximately 30 inches or 2.5 feet long from snout to tail.
Little Dwarf Lanternsharks measure quite small, as adult females grow to a mere 8 inches, which is tiny enough to rest snugly within your hand’s palm. Males are even smaller, reaching about 6.75 inches. These creatures have only been discovered in the Atlantic waters along the coasts of Colombia and Venezuela, at depths ranging from 283 meters to 1,440 feet.
These creatures resemble small versions of regular sharks, exhibiting similar characteristics. They boast a long, flattened skull with five gill openings on each side, as well as pectoral fins, pelvic fins, a long sloping tail fin, and two dorsal fins, each equipped with a distinct spinal ridge in front. The mouth is located beneath the head and slightly further back, housing between 25 and 32 rows of teeth on the upper jaw and 30 to 34 rows in the lower jaw. Their eyes are unusually large relative to their body size, allowing them to see clearly even a thousand feet below the surface.
Generally speaking, these creatures have a predominantly brown body with dark markings on their undersides, and they’re covered in tiny, tooth-like scales called dermal denticles. The term ‘dwarf lanternshark’, just like all lanternsharks, refers to their ability to emit light – a trait known as bioluminescence. They achieve this by using unique structures called photophores.
Dwarf Lanternsharks possess glowing spots on their fins and underside, illuminating the depths when darkness prevails. These photoluminescent areas could serve as camouflage for them, making it harder to spot against the dim surroundings. As lanternsharks approach the water’s surface, these light-emitting structures might aid in blending with the intermittent blue glow filtering down from above. Furthermore, they likely use these photophores to attract prey, employing their luminescence to draw small fish, minuscule cephalopods, and tiny crustaceans towards their diminutive jaws.
