Scientists find three glow-in-the-dark sharks

When it comes to animal abilities that humans would love to have, being able to glow in the dark has to be near the top of the list, right beneath flight and, of course, turning your skin into camouflage like an octopus. Scientists know about plenty of animals with what is known as bioluminescence, including fireflies and many species of deep-sea fish. Now, they can add three more to their list.

In a new study published in the journal Frontiers in Marine Science, researchers studying deep-sea sharks reveal that three species of sharks found off the coast of New Zealand exhibit the ability to glow in the dark waters where they live. Being sharks, they’re hunters but also potential prey for other species, so glowing in the dark might not seem like a very useful feature, but it actually is.

“Through a histological and pharmacological approach, the bioluminescence of three different shark species was investigated,” the researchers write. “Our results support evolutive conservation of light organ morphology and luminescence control. For the first time, luminescence was recorded and analyzed for the largest luminous vertebrate, D. licha and two lanternsharks, E. lucifer and E. granulosus.”

Many fish that live near the bottom of the ocean have glowing body parts that they use as lures to catch prey. Tiny dangling bits of glowing tissue belies the danger that the fish pose to their smaller prey, but the sharks in this study don’t glow to draw attention, but rather to avoid it.
