Not everything that glows is gold, it could be a sea turtle! With human brains going deeper and deeper into the blue, more creatures are being exposed with their bio fluorescence. The latest to be added to that list is the hawkbill sea turtle.
David Gruber, a National Geographic explorer from City University of New York, was the one who met with this unique hawkbill sea turtle, emitting green and red lights, while having his deep sea exploration during July. But it was only now that we are getting to know of it, as the footage of this bio-fluorescent turtle was outed only this Monday.
Scientists are yet to reach a conclusion on how bio-fluorescence works on animals. But simultaneously, they have been able to crack down most of the reasons for why bio-luminance exists in certain animal.
Both are different indeed, just like it is with the difference of terms luminance and fluorescence. Unlike the former phenomenon, fluorescence never involves self-creation of light, but only occurs with the absorption of light to be emitted later.
The process has been seen mainly with life forms under the ocean, like in corals and jellybeans. But it’s for the first time that the process has been discovered in a reptile.
That has even perplexed their task of finding the roots and cause for bio-fluorescence. An assumption among the bio-analysts is that they get to take more of the blue light being under water. Yet the real uses still remain unclear. Scientists believe there can be multiple reasons, like for luring prey, to defy predators, to give out signals and the like.
The case of the bio-fluorescent turtle is also believed to be a case of camouflage to skip the hunting jaws. And it does seem like nature has given it rightly; hawkbill turtles don’t represent a significant count among the sea population.
