Ghosts, Goblins and Living Fossils: A SharkTober Spooktacular! With Dr James Lea
It’s spooky season, which is basically a big ol’ excuse to visit some of our weirder and more mysterious species with their strange and fantastical adaptations. Think haunted-looking sharks that have remained unchanged since the time of the dinosaurs; a tiny terror with a mouth straight out of a Stephen king novel; a ray that can deliver 220 volts of electricity to its enemies and a deep-sea critter with a distinctly ghostly appearance and an alien-like third arm that extends out from the front of its head… We talk about all this and more with shark scientist, horror enthusiast and all-round ocean nerd Dr James Lea! Key timestamps 9.46: Cute but creepy - all things ghost shark (and their bizarre tenaculums) 20.55: The ancient, zombie-like frilled shark and all its teeth 27.50: Goblin sharks; the pink predator of your nightmares 32.53: Coffin rays, the electrifying ray that could give Uncle Fester a run for his money 42.53: The Greenland shark who stole Christmas? (And getting ‘shark drunk’) 48.56: A parasitic tangent into the shark-eating barnacle 51.30: The mysterious and diverse deep-water catshark family, viper dogfish, and the blackbelly lantern shark 58.04: Tiny terrors: cookie-cutter sharks!

Sawfishes: Ancient, Unique and on the Brink of Extinction with Dr Barbara Wueringer
October is famously spooky season – but did you also know it’s the month that we celebrate one of the funkiest groups of elasmobranchs? October 17th is International Sawfish Day, an event held every year to raise awareness of these wonderfully weird and seriously threatened animals. ‘What is a sawfish?’ I hear you cry. Well, fear not – this is an episode dedicated entirely to learning all about them. And to teach us all about these fantastical and mysterious creatures, our guest is Dr Barbara Wueringer, a scientist specialising in the behaviour, sensory ecology and biology of sharks and rays, with a particular focus and passion for sawfishes. She is the founder, director, and principal scientist of Sharks And Rays Australia (SARA), a non-profit research organization based in Cairns, Queensland, dedicated to not only the study of these species, but also the engagement of the public and local and Indigenous communities in their conservation. You can find out more about Dr Wueringer and the work of SARA here https://www.sharksandraysaustralia.com/ or by following @SharksAndRaysAU. Found a saw? You can report it to www.cytags.com (for sighting submissions in Australia) or https://www.sawfishconservationsociety.org/ (for international sightings).

Sharing the Water with Sharks with Luke Saddler
Many of us enter the water hoping to encounter sharks and rays, and maybe even get some prize images of our own – but how can we do it with as little impact on the animal as possible? In this episode, we discuss how to share the water with sharks safely, ethically and responsibly with wildlife photographer and filmmaker Luke Saddler, who has spent countless hours observing sharks in their environment and capturing their natural behaviours. We talk about how to: read body language, choose a responsible tourism operator, start out in wildlife film-making and become a ‘fly-on-the-wall’ – all while hearing some of Luke’s own incredible adventures in the field.

Caring for Cameroon's Sharks, Rays and People with Ghofrane Labyedh
Ghofrane Labyedh came to Cameroon in search of whales and instead discovered an overlooked conservation story: threatened sharks and rays were being landed in large numbers, yet little was known about the fisheries catching them. Since 2019, Ghofrane has worked alongside Cameroon’s coastal communities to understand these fisheries and the cultural, social and economic importance of sharks and rays. In this episode she shares stories of her work, which weaves together research, community-led conservation, policy and storytelling; culminating in an initiative where the fishers themselves play a central role in protecting the endangered species on their doorstep. She also discusses how she has taken this multi-layered approach in her new role as Lead Coordinator of the West and Central Africa Elasmobranch Coalition with the Manta Trust. Her work here will focus on bringing together researchers, organisations and practitioners from across 14 countries in the region to address the decline of sharks and rays, strengthening in-country capacity for research and monitoring, and enhancing policy and legal frameworks for endangered species.

A Closer Look at the Shark Fin Trade with Dr Diego Cardeñosa
The international trade in shark fins is a behemoth; vast, complex and difficult to disentangle. But for molecular and forensics expert Dr Diego Cardeñosa, one of the most powerful tools we have to tackle the fin trade is the tiniest part of a shark: their DNA. In this episode, we take a deep dive into Diego's research, which has been instrumental in understanding the nuances of the fin trade and securing better regulations for this billion-dollar industry. This includes the development of a portable, easy-to-use and inexpensive DNA ID kit (the "lab-in-a-backpack") that can help local officials identify endangered and protected species from just fragments of shark fin - all for under $2. We also talk about the problems with implementing international policy at a local level, the scale and complexities of the trade, and whether Diego is seeing any shifts in how the trade operates - for better or for worse.

The Unseen World of the Pelagic Thresher Shark with Rafid Shidqi
Few sharks capture the imagination quite like the thresher shark. They are well-known for their cartoonish appearance, “anxious-looking” faces and seriously cool hunting technique. But in scientific terms, we know very little about them – despite their endangered status. Rafid Shidqi is on a mission to change that. For the last eight years, he has led groundbreaking research on the elusive pelagic thresher sharks of Alor, Indonesia, whose preference for deep, pelagic habitats make them extremely difficult to study. In 2018, Rafid started the non-profit Thresher Shark Indonesia, working within remote, shark-dependent fishing communities to better understand and protect the species. Through acoustic and satellite telemetry and socio-economic studies, Rafid has made vital discoveries about not only the movements and behaviour of pelagic threshers, but also the communities who rely on them to make a living. Rafid’s story isn’t just about conserving a cool species – it’s also about empowering communities, opening pathways for local youth through conservation leadership, and finding sustainable solutions for shark-dependent fisheries.

Parasites! The World Inside of Sharks with Dr Bjoern Schaeffner and Dr Jaime Penadés Suay
Parasites have a bad rep. We often see them as harmful, exploitative, and just plain icky. But in the shark world, parasites are much more than just irritating hitchhikers. They are ecosystem engineers and important indicators of the health of not just sharks, but the entire ocean. And studies are starting to show some may actually benefit our sharky friends. Isla met with shark parasitologists Dr Bjoern Schaeffner and Dr Jaime Penadés Suay at Sharks International, Sri Lanka, where they were hosting a workshop on shark parasites. Together, they discuss what parasites we might find in and on sharks, their critical ecological and biological roles, and why on earth we should care about them, before heading to an outdoor dissection in the seaside city of Negombo to explore, hands-on, the world inside of sharks.
