Black dogfish [Etmopterus]

Description

Etmopterus, known as the black dogfish, encompasses a genus of sharks within the Squalidae family. These small to medium-sized sharks are recognized for their dark coloration, which ranges from brown to black, and for the presence of photophores that produce light. This bioluminescence is thought to play a role in camouflage, communication, and prey attraction. Black dogfish are found in deep waters worldwide, from tropical to temperate regions. They exhibit a variety of feeding strategies, including active predation and scavenging.
