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 ..read more

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 h ..read more

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 ..read more

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 passe ..read more

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.  You can follow Lucille on twitter (@sharkslikejazz), instagram (@lucillechapuis) and via her website, www.sharkslikejazz.com.  If you liked this episode, please consid ..read more

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 ..read more

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. You can find additional resources in the shownotes: www.saveourseas.com/worldofsharks/podcast You can keep track of when our grants and funding opportunities are announced by followi ..read more

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 reproducti ..read more

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 ..read more

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 al ..read more
