Two manta ray species and five shark species - the oceanic whitetip shark, the porbeagle shark and three types of hammerheads - should be able to swim a little safer, thanks to new protection in the form of a Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) regulation.
Beginning September 14, permits are now required for the international trade of these rays and sharks, to ensure "they have been harvested sustainably and legally." For the 180 parties that comprise CITES - from Afghanistan to Zimbabwe - the export of the gills, fins or meat of these species is no longer allowed without permits from national authorities. When exports do occur, these trade data will be made publicly available, according to a CITES press release.
Considering the roughly 100 million sharks killed annually, there's surprisingly little information on who is hunting which sharks where. "CITES is really the only way we have to monitor the trade and the fins of these species," says Stony Brook University shark expert Demian Chapman, in a video accompanying the announcement.
