Wow.... JAWS has a lot of catching up to do! What next, sharks that are Invisible and 'Fly'...?? Nature is pretty amazing, too bad I'm now hiding in my basement to enjoy it. Darn invisi-shark!
The real name of the phantom hunter is Etmopterus spinax or velvet belly lantern shark. It lives in the deep waters of the northeastern Atlantic Ocean. According to a study published in the Journal of Experimental Marine Biology and Ecology, the shark becomes invisible by regulating the photophores underneath its body. This makes their belly glow matching the color of the Sun's light above them. As a result, prey or predators looking up from lower depts are not able to see them.
