First try and 4 guesses here!
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.

Join the Global Coalition to Halt Shark and Ray Extinction
Over 35% of sharks and rays are threatened with extinction — most are declining due to overfishing. Urgent, coordinated action is needed.
Remember that first global record of megamouth shark pups? It's finally published in a scientific journal! Read all about it here: doi.org/10.31398/tpjf
This study was partly supported by @mwwphilippines.bsky.social #AtingPating grants. Congratulations to the authors!
