About the Blurred Lanternshark

The blurred lanternshark is a species of dogfish shark found all over the world, but mostly in the warm and temperate waters of the Indian, Pacific, and Atlantic Oceans.

Like all lanternsharks, they’re small deep water sharks known for the light-producing photophores on their bodies. The photophores are concentrated mostly on their belly and it works as counter illumination, making the shark seem brighter to match their backgrounds. This makes it easier for the lanternshark to stalk prey.

The live in deep waters and have been found at depths of 163 to 1000 m.

They’re ovoviviparous. Pups are born at 16 cm and grow to a maximum length of 67 cm. Very little else is known about their biology. 

Their name comes from their irregularly arranged dermal denticles.

Since the species is widespread and have no commercial value, they’re currently considered Least Concern by the IUCN.
