Conservation is often more about understanding people than studying the animals we are trying to protect. In this episode we learn from Dr Hollie Booth, research fellow at the University of Oxford, who has worked extensively with small-scale fisheries in Indonesia, the world’s largest shark fishing nation. Hollie’s work aims to disentangle the drivers of shark fishing in order to find solutions that have positive outcomes for both sharks and coastal communities. Here, we discuss the complexities of fisheries and the many reasons why someone might catch and trade sharks. And, we talk about the importance of finding conservation strategies that are socially just as well as ecologically effective.

The ocean is warming at a rapid pace. This year (2024) began with the highest global Sea Surface Temperature (SST) on record, and scientists are already warning of mass coral bleaching events and other worrying consequences for marine life. But how could rising temperatures impact sharks, particularly in the early stages of life when they are most vulnerable? PhD student and “mother-of-sharks” Noémie Coulon is trying to understand the effects of ocean warming and acidification on baby sharks, using an egg-laying species – the small-spotted catshark – as an example. In this episode, we follow her work as she raises catsharks in the lab, testing the effects of different environmental conditions at key stages in their development.

In February 2024, a round stingray from a small, rural aquarium in the middle of a shopping mall unexpectedly took the world by storm. She was pregnant, but how this had happened was a complete mystery - there were no male stingrays in the tank, nor had there ever been...

In this episode we are joined by scientist and science communicator Dr David Shiffman (@whysharksmatter) to examine Charlotte's case. We go deep into the various theories that could explain Charlotte's pregnancy to get to the bottom of what really happened. No, a shark did not get a ray pregnant, but what did happen is even more fascinating. It's a good excuse to take a deep dive into the more unusual methods of shark and ray reproduction, including the super cool zoological phenomenon that is parthenogenesis!

The international shark fin trade is a billion-dollar industry. It is also driving declines in shark populations around the world. In this episode, we are joined by Luke Warwick, expert in global shark policy, to learn how CITES - an international agreement between governments to regulate trade in endangered species - could help protect sharks and rays from overexploitation. In particular, we discuss a landmark vote that occurred in 2022, which saw 90% of the fin trade come under regulation almost overnight. Luke walks us through what has happened in the year since, from getting the vote passed to implementing the new regulations at local level. And, we discuss some of the trials and tribulations of trying to get 100+ countries to agree on something, especially when most of them have a vested interest...

Do sharks have ears? Are they good listeners? What are they listening for? Do great white sharks get freaked out by orca sounds? And what kind of music do sharks like?! We cover all this and so much more with bio-acoustician and shark hearing expert, Dr Lucille Chapuis. Join us for a fact-filled episode that includes disco sharks, curious humpbacks, putting sharks in 'sleepy-time baths' and R2D2 with a throat problem.

Time travel. Ancient coral reefs. Shark sleuthing. The AMAZING properties of shark skin...this episode has it all! We're chatting with Dr Erin Dillon, conservation paleobiologist and researcher at the Smithsonian Tropical Research Institute. Erin's work uses fossilised shark skin (fancy term: dermal denticles) as a window into the past, to understand what kinds of sharks were around on coral reefs thousands of years ago and how that has changed over time. It's a fascinating deep dive into shark life before humans made their mark, and an insight into what healthy reefs could look like with a little bit of help.

It's our 50th episode!! To celebrate, host Isla is joined by shark scientist and CEO of the Save Our Seas Foundation Dr James Lea to talk about the amazing evolutionary success of sharks and their relatives. We talk about just how much sharks have had thrown at them over the 440 million years they've existed on this planet (super volcanoes, ice ages, the terror of plants and a mass extinction event called the 'Great Dying'!) and discuss their super-powered adaptations and efficient body plans. Plus, we answer a listener question: how can I get my friends into shark conservation?

Starting out on your own career journey can be a little daunting, which is why we’ve put together this special episode of World of Sharks, filled with advice, experiences and anecdotes from the guests of season 4. We talk about how to make your dreams of working in shark science and conservation a reality – from how to approach professors, to finding your niche, to overcoming setbacks and staying true to yourself.

Plastics. Oil spills. Industrial chemicals. Herbicides. Pesticides…the list of substances that we have dumped in the sea is endless. But scientists are only just beginning to understand the true extent of the impact of marine pollutants on marine life. Fish biologist and SOSF project leader Franco Cristiani is investigating the effects of harmful pollutants on chondrichthyans, using the American elephant fish (a chimaera) as a model species. We invited Franco onto World of Sharks to discuss this important research and learn about the potential consequences of marine pollution on the reproductive health, immune function and overall survival of sharks and their relatives. And, of course, we take some time to talk about the gloriously weird and funky American elephant fish!

We’re heading back to the Seychelles this week to chat with research and programme directors for the Save Our Seas Foundation D’Arros Research Centre (SOSF-DRC), Dr Rob Bullock and Henriette Grimmel! Both Rob and Henriette have lots of experience and knowledge in the application of scientific research to marine policy, spatial planning and conservation. And, where they live and work – D’Arros, located in the outer islands of the Seychelles – is the perfect example of how science can be applied to protect and restore marine ecosystems. We talk about the magic of D'Arros, the impressive suite of long-term monitoring programmes carried out by the SOSF-DRC, and the long and complex process of designating and managing a Marine Protected Area (MPA). There are also cameos from the Aldabra giant tortoises, baby sharks, Sir David Attenborough and a VERY friendly manta ray called Jackson.
