lanternsharks

Lanternsharks are a family of small sharks belonging to the order Carcharhiniformes, most of whom are found in the deep sea. They are named for the bioluminescent organs called photophores that are scattered across their undersides, resembling the lights of a lantern. These photophores are thought to be used for camouflage, attracting prey, or communication.

There are currently over 30 described species of lanternshark, primarily in the genera Etmopterus and Trigonognathus. They are characterized by their slender bodies, large heads, and often prominent dorsal fins. Many species possess a spine in front of each dorsal fin, which can be venomous. Their diet typically consists of small fish, squid, and crustaceans.

Lanternsharks are widely distributed in oceans around the world, inhabiting depths ranging from the continental shelf to the abyssal zone. They are generally not considered a threat to humans due to their small size and deep-sea habitat. Research on lanternsharks is ongoing, with scientists continuing to discover new species and learn more about their unique adaptations to life in the deep ocean.
