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!

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.

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.

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.

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.Find out more: https://threshershark.id/en/ (@threshershark.id on instagram) and @rafid.shidqi

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.

We're diving back into our mailbag to answer more of your burning sharky questions! In this episode we address all sorts of fascinating queries such as how bioluminescence evolved in sharks, which species are capable of breathing while they’re not swimming, and whether sharks are really older than trees. Plus, we take deep dives into several awesome species – great white sharks, grey reef sharks, pocket sharks and of course, James’ favourite, the velvet belly lantern shark.
Specific question timestamps:
Q1: Are there any shark species that are showing signs of adapting well to climate change? [3.36 – 10.21]
Q2: Has there ever been more observations of any of the two species of Mollisquama (pocket sharks)? [10.31 – 13.20]
Q3: How did bioluminescence in species like the pocket shark evolve? Was it independent, or did their last common ancestor have bioluminescent fluid? [13.40-15.11]
Q4: We rarely hear about white sharks in the vicinity of South America, either ocean, with the exception of seasonal migrations of NA white sharks into the US South Atlantic coast and Caribbean. My question is: why not? [15.22 – 21.49]
Q5: Which shark species can stay still and breathe through buccal pumping? [21.59-28.44]
Q6: Which species of shark and ray are most closely related? [28.54 – 37.50]
Q7: What is the most surprising thing you’ve learnt in your career (when you first started, vs. most recently)? [37.58 – 44.58]
Q8: Shark [bite incidents] often go unreported for various reasons despite the best efforts of educational institutes to accurately record them. What do you think the real number of global [incidents] might be? [45.06-52.14]

Art has the power to change perspectives, spark dialogue, and raise awareness of the complex issues facing our ocean. This is exactly why PangeaSeed was established. Since its inception in 2010, PangeaSeed has brought together local artists and their communities to collaborate on large-scale, vibrant public artworks on the walls of their towns and cities, depicting the ocean, her inhabitants, and the challenges she faces, in line with PangeaSeed's mission to bridge art and science. Over the last decade, over 500 murals have been created in locations across the world. Ahead of their travels to Seychelles, Isla sat down with executive director and director of operations for PangeaSeed, Tre and Akira, to discuss the intersection of art and ocean conservation, the importance of community and connection, and how sharks started an entire movement.

The Maldives has served as a shark sanctuary for 15 years, and is now one of the most diverse regions for sharks and rays in the world. But with great success comes a new problem: conflict with humans. Fishers are reporting a loss of some of their catch to sharks, an issue known as depredation. For her PhD, SOSF project leader Mina Hatayama is seeking to understand depredation in the Maldives, studying shark behaviour and how it impacts local fishers and their attitudes towards sharks. She will also be asking the very intriguing question of whether hotter sharks are hungrier sharks, exploring the potential role of ocean warming in these increased depredation incidents, as well as working closely with the local fishing community to understand their perspectives and co-develop sustainable solutions.
In this episode, we dive into the challenges of humans and sharks sharing space and resources. It’s a really insightful conversation that weaves together all kinds of issues, from human attitudes and shifting baselines, to the influence of global threats such as climate change on human-wildlife interactions. We also discuss how complex and delicate these situations can be, and the realities of navigating an interdisciplinary project.

Sometimes called the 'couch potatoes of the sea', nurse sharks are famous for their laid back attitude to life spending most of their days cosied up in piles, napping. But their gentle, docile nature doesn't make them any less special. In this episode, we sit down with SOSF project leader and PhD Researcher Sergio Madrigal Mora - who has spent a lot of time hanging out with the Labradors of the shark world - to discuss how nurse sharks are perfectly adapted to life in the tropics and why they form 'cuddle huddles' on the sea floor. And, we learn more about Sergio's research into the influence of changing temperatures on the movements of Pacific nurse sharks in Costa Rica's St Elena Bay.

We know sharks have incredible senses, but just how good is their eyesight? In this episode, we explore the world through a shark's eyes with fish vision expert Dr Lily Fogg. How does fish vision compare to our own? How do the eyes of a fish living on a vibrant coral reef differ from those hanging out in the murky depths? And do sharks see in technicolour, or multiple shades of grey?
We also take a dive deep into Lily's most recent research, which investigated the eyes of the world's longest living vertebrate: the greenland shark. Her findings challenge a commonly held perception of these ancient creatures, and push the boundaries of what we thought was physiologically possible...

The conversations that shape the fate of sharks and rays rarely happen in quiet laboratories or out at sea. More often, they unfold in fluorescent-lit halls, behind nameplates and microphones, inside sprawling congress centres where global decisions about nature are made. At the IUCN World Conservation Congress, surrounded by thousands of delegates debating the future of biodiversity, host Isla sat down with SOSF Scientific Advisor Sarah Fowler and Chair of the IUCN Shark Specialist Group, Dr Rima Jabado, to discuss how far we’ve come in the race to save sharks and rays from extinction – and what steps we need to take next to ensure their future on this planet.

From a shovel to a mallet, and even an aeroplane - the hammerheads really do win the prize for some of the most bizarrely shaped sharks out there. But why do they have such oddly-shaped noggins? What do they eat? Where do we find them? And why are one of the most charismatic groups of sharks in the world also one of the most threatened?
In this episode we are joined by Dr Kelly Kingon, Associate Professor at the University of the Bahamas, SOSF project leader and co-director of the non-profit CHaPO (Conserve Habitats and Protect Organisms). Kelly has been trying to find scalloped hammerhead nurseries in Trinidad and Tobago to inform conservation and management strategies for this heavily fished species. We discuss the amazingness of hammerheads, their unique adaptations and conservation status, before zooming in on Kelly's research to discover what's happening to baby hammers in the warm waters of the Carribean.

Tagging hammerheads, tracking silky sharks and exploring a remote coral paradise in the middle of the Gulf of Mexico…This week, we’re diving into the fascinating world of shark trophic ecology with PhD researcher and SOSF project leader Brett Sweezey! Brett is investigating the interactions between predators and prey, and how they influence where sharks go amongst the unique habitats of the Flower Garden Banks National Marine Sanctuary. Join us as we discuss the innovative methods Brett is using, some fascinating early findings, and the challenges and triumphs of studying these incredible creatures in their natural habitat.

A turtle that looks like a pig, and a shark that looks like a plane...in this episode, we're heading to the colourful, diverse lands of the Kikori River in Southern Papua New Guinea to meet researcher and director of the Piku Biodiversity Network (www.pikubionet.org.pg). In 2018, Yolarnie expanded the PBN - which originally focussed on the community-led conservation of the endangered pig-nosed turtle - to include the 45 species of shark and ray that can be found in the Kikori river system. These species include the unusual and understudied winghead shark, one of the few sharks that passes between salt and freshwater to give birth to its young.

We're taking to the skies to find out what great white sharks get up to when no-one's looking...
From his drone’s vantage, Carlos Gauna — AKA The Malibu Artist — has captured previously unrecorded behaviours of one of the ocean’s most captivating predators, the great white shark. His footage has fascinated viewers from across the globe, challenged misconceptions of white sharks, and even altered Carlos’ own perspective of the species. In this episode we talk about some of these behaviours; from a shark apparently 'eating' kelp to their interactions with dolphins and people. And, we discuss the moment that Carlos captured the first possible newborn white shark on camera - a key discovery that could secure important protections for white sharks in the area.
You can follow along with Carlos' work and see all his incredible footage here:

Tagging tiger sharks, seamount navigation, and a great white shark called Princess Sparkles... This week, we're diving into the fascinating world of shark movement ecology with research scientist Dr Sammy Andrzejaczek to explore how and why sharks move about the oceans - in particular zooming in on their vertical space use and asking why some sharks take frequent dives to depths of over 1,000 metres. We also discuss the potential effects of the lunar cycle, and what white sharks are up to off the coast of central California. And, we take you behind the scenes as Sammy explains some of the different technologies that she uses to carry out this research and live her dream working with these incredible animals in the wild.

We're gonna need a bigger podcast...
In honour of the 50th anniversary of the release of Jaws - one of the most iconic shark movies of all time - we are bringing you a very special bonus episode wholly dedicated to the film. Host Isla is joined by two jawsome guests: shark scientist and science communicator Amani Webber-Schultz (@curly_biologist), and social scientist and Associate Professor in public policy, Dr Chris Pepin-Neff (@csyd2202). Together, they discuss the cultural impact of Jaws and its negative effects on public perceptions of sharks and shark conservation, as well as its positive influences - including sparking the careers of a whole generation of shark scientists. And, they take a deep dive into the film itself, reliving their favourite scenes, sharing behind-the-scenes facts, and dreaming up their own pitches to Hollywood.
