Experts call for shark awareness

Jason Farmer for RedOrbit.com There are a number of sharks that have specialized light-emitting organs on their undersides that allow them to glow in the darkest depths of the ocean. In fact, according to researchers, at least 10% of all known shark species are luminous, and this ability is one of the most mysterious areas of shark biology. A new study of a tiny predator known as the Smalleye pygmy shark (Squalious aliae), led by Dr Julien Claes from the Catholic University of Louvain in Belgium, suggests this ability may have evolved from a shallow water ancestor and may yield a greater understanding of the specific molecular mechanisms sharks use to achieve this bioluminescence. Pygmy sharks only grow to 22 centimeters in length and swim many hundreds of feet below the surface in the Indian and western Pacific oceans, so they can be very difficult to locate and study. When the world's smallest sharks are found, researchers observe a bluish glow on their underbellies. Dr Claes also wanted to compare this abi
