If any further proof was needed of the vast unexplored wonders of the deep sea, this would fit the bill: researchers in new zealand have discovered three new shark species that glow in the dark.
And in the dark of the deep ocean, glowing can help creatures attract mates, lure prey or confuse predators. Marine biologist dimitri deheyn has spent years studying how marine animals use light, focusing, in particular, on a shark species that glows.

The swell sharks are by no means the first underwater animals to glow in the dark; gruber was part of a team who discovered biofluorescence in over 180 species of fish.
There are only two families of deep-sea sharks that are able to glow in the dark by bioluminescence. They are the kitefin sharks (dalatiidae) and the lantern sharks (etmopteridae). How do the sharks glow? organisms can appear to glow in the dark in a few different ways.
Researchers have known for a while now that some sharks can glow in the dark. Until recently, it was only thought that around a dozen species lit up in the dark depths of the ocean.
Both sharks have dark and light tones, and it turns out that in both species’ lighter parts (and their white spots) were what caused the fluorescence.
The three glow-in-the-dark sharks live in the twilight zone, between 200 m and 1000 m in depth. This study calls it the “realm of bioluminescence” because light from the sun is not able to get to that level. It is not fully known why the kitefin glows in the dark, so additional studies are necessary.
In the depths of the sea, certain shark species transform the ocean's blue light into a bright green color that only other sharks can see--but how they biofluoresce has previously been unclear.
Scientists have found three species of sharks living in the deep waters off the east coast of new zealand that glow in the dark.
Mallefet, stevens and duchatelet scientists say they have found that three deepwater shark species living off new zealand glow in the dark.
Mar 3, 2021 scientists have taken the first ever photos of a glow-in-the-dark shark producing its own light.
But news out of the science world today offers up something completely different: a group of international scientists from the united states and israel discovered that certain types of sharks actually glow in the dark underwater to attract a mate.
This has been known for a while (at least 20 years) that some fish do this but the new thing is that sharks can do this. Where the sharks are there is a very dim light, right at the edge of the darkness. Rh ckiw on the bottom allow them to blend in with the faint light coming from above.
And now researchers have identified the largest glow-in-the-dark species with a spine — on land or sea — that.
Aquapparel glow in the dark shark, glow in the dark sharks the simple answer: they do not “glow in the dark” – they transform the light.
Among the three glowing sharks, the kitefin shark is now the largest-known luminous underwater creature. The shark is usually found swimming 300 meters (984 feet) below sea level and preys on smaller sharks, ground fish and crustaceans.
The sharks don’t glow uniformly across their entire bodies. Instead, the majority of the luminescence is isolated on the bellies of the animals. When viewed from below, against the dim backdrop of the surface, the sharks’ glowing bellies allow them to essentially disappear.
(cnn) sharks are known to stalk and sniff out prey before they attack. But all this newly discovered shark species has to do is glow in the dark, and the prey comes to them.
(cnn) glowing green sharks swim in the dark depths of the ocean thanks to an entirely different kind of biofluorescence than other marine animals.
Sharks are known to stalk and sniff out prey before they attack. But all this newly discovered shark species has to do is glow in the dark, and the prey comes to them.
Scientists studying sharks off new zealand have discovered that three deep-sea species glow in the dark – including one that is now the largest-known luminous vertebrate.
Scientists recently snapped images of three species of shark living in the pacific ocean off of new zealand that glow in the dark.
