The last proposal for sharks has just passed at #CITESCoP20. Gulper Sharks have been adopted into Appendix II of CITES.

This marks a major victory for sharks and rays as all proposals have been adopted!

Title page for an IPBES Sustainable Use Assessment report on Deep-Sea Sharks. The image features a silhouette of a shark swimming in deep turquoise waters, creating an atmospheric underwater effect. The main title "Deep-Sea Sharks" appears in large white text at the top, followed by the subtitle "Conservation is crucial for vulnerable shark populations" in mixed fonts. The IPBES logo appears in the bottom right corner, with the text "Science and Policy for People and Nature" beneath it. The overall design uses a deep teal background that evokes the deep ocean environment.

#DidYouKnow ? Shark reproductive rates and recovery potential are known to decline when depth increases & population depletion risks exist, even when exploitation (targeted or incidental) rates are low.
