BONUS EPISODE - 50 Years On: Was Jaws Really Bad for Sharks? With Amani Webber-Schultz and Chris Pepin-Neff

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.

White Sharks: Secrets of a Top Predator with Dr Alison Kock

They are the most iconic shark species of all time, known for their strength, hunting prowess, and long-distance travel. But there is a lot more to great white sharks than their reputation. They are not the mindless killers that the movies would have you believe – in fact, they are a highly curious and elusive species who continue to surprise us. And someone who knows white sharks inside out is Dr Alison Kock, a marine biologist who has spent the last 20 years studying their behaviour and ecology. In this episode, Dr Kock shares everything she knows about the world's largest predatory fish, including a scientific finding that's hot off the press...

06.08 - 16.00: Alison's career and passion for sharks

16.00 - 30.00: Great white shark physiology, ecology, and behaviour

31.50 - 40.00: Zooming in on False Bay and Alison's research

41.30 - 54.00: Relationships between humans and white sharks

Filling the Gaps to Protect Sharks in Angola with Ana Lúcia Furtado Soares

This week on the World of Sharks podcast we are meeting Ana Lúcia Furtado Soares, founder of the Angola Elasmo Project - a grassroots initiative focussed on the research and conservation of sharks and rays along the Angolan coast – to discuss the joys and challenges of building a project from scratch, working with data-poor fisheries and the importance of empowering local voices.

Forensic Fisheries: Using DNA to Investigate the Trade in Shark Liver Oil with Dr Madeline Green

The trade in shark liver oil is an invisible threat to sharks. Not only is there limited research on the topic, but liver oil is notoriously difficult to track and trace. Enter Dr Madeline Green, molecular fisheries ecologist and Principle Investigator of the Forensic Fisheries Lab at the University of Tasmania. Madi is working to apply protocols from the tracing of olive oil to extract DNA from shark liver oil samples, in order to identify species and help monitor this complex trade. In this episode, we learn all about Madi's research, and how the trade in liver oil is presenting a significant threat to deep-water sharks.

Hungry Sharks? How a Shark's Digestive System Works

Spiral intestines! Curly poop! A shark that eats plants! And…turning your stomach inside out because you ate something dodgy?! In this episode we explore the ins and outs of a shark’s digestive system with animal physiologist Dr Samantha Leigh (@sea_science_sam), an expert in all things shark gut. We learn how a shark’s digestive system is designed for maximum efficiency, the different ways in which they ingest their hugely diverse diets, and how some sharks are able to survive weeks – sometimes months – without a meal. We also take a deep dive into Dr Leigh’s research on the bonnethead – a shark known to chow down on seagrass – and her recent SOSF-funded project, which is using the shark spiral intestine as a model to address one of our greatest environmental conundrums: the removal of microplastics.

Epaulette Sharks: The Sharks That Can Walk On Land with Faqih Akbar Algozali

Why swim when you can just walk from a to b?! This week, we are taking a closer look at the "walking" or epaulette sharks, a group of nine species who have evolved a slightly unusual way of getting around. We're joined by Faqih Akbar Alghozali, co-founder of Elasmobranch Project Indonesia (EPI) and SOSF project leader, who has lots of stories to share from his time in the field with the Kalabia, or Raja Ampat epaulette shark. Faqih and his team are trying to understand more about this poorly studied species, who are endemic to this remote paradise.

The Fascinating and Weird World of Shark Eggs with Cat Gordon

Join us for a slightly different easter egg hunt, as we go in search of shark eggcases! From tiny catshark eggcases no bigger than your index finger, to a skate that lays eggs larger than your head and even an egg that looks (and functions) like a corkscrew - we explore them all with Cat Gordon, Senior Conservation Officer for The Shark Trust. And, we learn about one of the longest running citizen science projects for sharks, rays and skates: The Great Eggcase Hunt.

Electroreception: The Shark's Sixth Sense with Professor Stephen Kajiura

In this episode, we are exploring the ‘sixth sense’ of sharks – electroreception! We are joined by sensory biologist and shark elasmobranch expert Dr Stephen Kajiura, Professor in the Department of Biological Sciences at Florida Atlantic University (FAU) to discuss how sharks are able to detect minute electrical signals and use this sense to pinpoint prey with mind-blowing accuracy. We also get deep into functional morphology, zooming in on the Ampullae of Lorenzini and the unique morphology of the hammerhead. And, we chat about how electroreception doubles up as a kind of internal shark sat nav, helping them to navigate entire oceans without any landmarks to speak of.
