Biofluorescence is commonly known among many jellies, corals and other marine organisms, but less commonly reported in fish. New Ceratosaur Species Unearthed in Brazil.

The molecules behind the Chain Catshark's biofluorescence have been identified by two biologists, David Gruber and Jason Crawford. Catsharks, such as the Swell Shark (Cephaloscyllium ventriosum) from the eastern Pacific and the Chain . Chain Catshark, Photo credit. Biofluorescence is widespread in marine fishes, although not all species have the ability to see it. Chain Catshark - It isn't so natural to find biofluorescence in the vertebrates. This image taken in 2015 by David Gruber, a professor at City University of New York, shows a glowing chain catshark at Scripps Canyon off the coast of San Diego California It may not sound like the best way to go incognito, but some species of shark that lurk on the ocean floor glow a bright green hue visible to others of their kind. Image Source: Scientific Reports. Biofluorescence has recently been found to be widespread in marine fishes, including sharks. "The exciting part of this study is the description of an entirely new form of marine biofluorescence from sharks - one that is based on brominated tryptophan-kynurenine small-molecule . Biofluorescence has recently been found to be widespread in marine fishes, including sharks. "This work further confirms that biofluorescence has repeatedly evolved across the animal tree of life and that the . Biofluorescence like this occurs when an animal absorbs light from an outside source like the sun, and then reemits it in a different color, in this case neon green.
