Some Sharks Glow in the Dark

If you can see a shark coming, does it make it less or more frightening? Of course it's terrible when something appears out of nowhere and attacks you, but what if you can see it coming and are helpless to stop it? And in light of that, how frightened would you be of a shark that glows in the dark?

Because so few organisms in our environment are able to light, bioluminescence is still somewhat of a novelty to us. There are more than 1,500 different types of fish that can produce light in the ocean. These fish are typically found in deep waters, and they aren't usually sharks. Some of them, though, are. Three species in particular were found off the New Zealand coast. The kitefin shark is one of them and may reach lengths of almost six feet.
