Four Unique Technologies Saving Sharks from Extinction #sharkweek @sharkweek #sharks

A team of scientists led by Stony Brook University's Institute for Ocean Conservation Science has figured out that dusky sharks and copper sharks -- both heavily hunted for their fins, with the dusky shark species classified as threatened by the IUCN -- have distinct populations living along different areas of coastlines. By looking closely at the "zip code" embedded in the DNA of the fin, the researchers can pinpoint from which population that shark came, and therefore get a step closer to finding out who is exploiting the species. This strategy can be expanded to other shark species with similarly distinct populations -- and that can go a long way in pointing out where laws against shark fishing need to be enacted or better enforced.
