Glowing sharks caught on camera for first time

One in ten shark species are bioluminescent and now for the first time glowing sharks have been caught on camera. Check out this video from Jérôme Mallefet at the Catholic University of Louvain in Belgium. I’ve written several stories for National Geographic News about Jérôme’s work, together with Julien Claes.

They’re uncovering fascinating things about these illusive deep sea sharks – seems they use bioluminescence as camouflage to hide their silhouettes in the deep sea. And a new study, suggests the same sharks also use light to warn off predators – illuminating spines on their backs, like little light sabers.
