by This frightening squid lives 2,000 to 4,000 feet (600 to 1,200 meters) below the surface of tropical and temperate oceans.
It can precisely control the duration and intensity of flashes emitted by its bioluminescent arm tips, and waves these flashbulbs to disorient attackers.
At other times, the squid hides in the dark by pulling its webbed arms over its head so only the dark side of its "cloak" is exposed giving the "vampire squid" its name.
However, this foot-long cephalopod is no bloodsucker; scientists don't yet know what it eats.
