It's spooky season! And we're taking the opportunity to celebrate some close relatives of sharks and rays who don't get talked about as much as they deserve: the chimaeras. Also known as ghost sharks, spookfish, ratfish and rabbitfish, these ancient creatures glide in the dark of the deep ocean, much of their life shrouded in mystery. Helping us learn more about them is our guest, fish biologist and SOSF project leader Dr Luz Erandi Saldaña Ruiz. In this episode we learn all about Luz's work, which aims to improve the management of data-poor and data-limited fisheries in Mexico and find out all there is to know about the sharks' enigmatic cousins, who Luz works closely with. Digressions include Tim Burton's A Nightmare Before Christmas, sea creatures that defy reality, and a shark with starry skin.   You can follow Luz on Instagram (@erandiscienceart), twitter (@Sarudanya) and Facebook (ErandiScienceArt).
