description Blackbelly lanternshark Overview
The blackbelly lanternshark (Etmopterus lucifer) is a species of deepwater dogfish shark in the family Etmopteridae. First scientifically described from Japanese waters in 1902, this shark inhabits the bathypelagic zone of the Pacific and Indian Oceans. Like other lanternsharks, it is distinguished by the presence of specialized ventral photophores that produce a blue-green bioluminescence. This biological mechanism provides counter-illumination, allowing the shark to camouflage its silhouette from predators below.
