FfFfFfFF 58,083 Posted March 3, 2021 Share Posted March 3, 2021 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. Bioluminescence – the production of visible light through a chemical reaction by living organisms – is a widespread phenomenon among marine life but this is the first time it has been documented and analysed in the kitefin shark, the blackbelly lanternshark, and the southern lanternshark. The researchers, from the Université Catholique de Louvain in Belgium and the National Institute of Water and Atmospheric Research in New Zealand, said the findings had repercussions for our understanding of life in the deep sea; one of the least-studied ecosystems on the planet. The sharks all live in what is known as the mesopelagic or “twilight” zone of the ocean, between 200 and 1,000 metres deep, beyond which sunlight does not penetrate. Seen from below, the sharks appear backlit against the bright surface of the water, leaving them exposed to potential predators without any place to hide. Researchers suggest these three species’ glowing underbellies may help camouflage them from any threats that might strike from beneath. https://www.theguardian.com/environment/2021/mar/02/giant-luminous-shark-researchers-discover-that-three-deep-sea-sharks-glow-in-the-dark Link to post Share on other sites More sharing options...

The animals adapted to the dark conditions by developing the ability to project their own light. Link to post Share on other sites More sharing options...
