Etmopteridae is a family of dwarf-to-medium sized sharks found nearly worldwide. This family has over 50 species, including the deepest known shark species found at a depth of 4500 meters. As their name implies, some species of Lanternsharks exhibit bioluminescence on their bellies, flanks and fins. In short, they actually glow! They use their photomarkings to blend in to ambient light (called counter-illumination), for defense, and to communicate with other sharks of their own species.
