World of Sharks

Building Safe Spaces for Sharks, and Shark Scientists with Jasmin Graham

We welcome back shark scientist and CEO/Co-Founder of Minorities in Shark Sciences, Jasmin Graham, and celebrate the release of her new book, Sharks Don't Sink: Adventures of a Rogue Scientist. We talk about the incredible adaptations and resilience of sharks, the glorious weirdness of sawfishes - a species Jasmin has worked closely with - and why Jasmin feels innately connected to sharks and compelled to protect them. We also talk about the barriers faced by gender minorities of color in STEM fields, and Jasmin's journey to continue science outside the confines of traditional academia. On this journey, Jasmin co-founded Minorities in Shark Sciences (MISS) with Carlee Jackson, Amani Webber-Schultz and Jaida Elcock, to promote diversity and inclusion in shark research. We discuss how MISS has grown into a global community, and how Jasmin and her fellow co-founders have built a safe, accessible and welcoming space for the good of people and sharks.

In the Field: Basking Sharks with Dr Alexandra McInturf

We are so excited to share with you a very special bonus episode of World of Sharks! Join us as we head into the field in search of the second largest species of shark in the world: the basking shark. We’ll be heading out on the boat with Dr Alex McInturf (@drsurfnturf), shark scientist at the Chapple Big Fish Lab (@big_fish_lab), SOSF project leader and project coordinator for the Irish Basking Shark Group (@baskingirish). You'll be right there with us as we conduct some basking shark research, and you'll learn what it's like to tag, track, ultrasound and swim with a 32 foot (10m) shark in the wild.

Angel Sharks: Masters of Stealth and Critically Endangered

This week we are diving into the world of angel sharks, the second most threatened group of elasmobranchs in the world. Joining us is co-founder and co-lead of the Angel Shark Project, Eva Meyers, and project coordinator for the Angel Shark Project: Wales, Jake Davies. In this episode we learn all about angel sharks, their super-powered ability to “disappear” and ambush prey, and the work of the Angel Shark Project which aims to protect these unusual sharks throughout their range.

Around the ocean in 80 sharks with Dr Helen Scales

Sharks with beards. Deep sea sharks with glow-in-the-dark bellies. Sharks that take on submarines. Sharks that walk instead of swim and rays with a hedge trimmer for a nose…this episode has it all! We explore the fantastic diversity of sharks and their relatives (and of all marine life!) with marine biologist, scientific writer and broadcaster Dr Helen Scales, ahead of the release of her new book, What the Wild Sea Can Be. Join us as we travel from the ocean depths to the shallowest rockpools, meeting a colourful bunch of characters along the way.

Exploring Galápagos, the sharkiest place on Earth with Pelayo Salinas de León

Come with us on a voyage to one of the most remote, biodiverse and "sharkiest" places on the planet with leading expert Pelayo Salinas, co-principal investigator of shark ecology and conservation at the Charles Darwin Foundation and Save Our Seas Foundation project leader. In this episode we go on a dive to observe scalloped hammerheads visiting their after-work spa, get booped by the bouncer of the reef, Galapagos sharks, and swim alongside the world's largest fish. And, if that wasn't enough, we head off on an expedition into the deep to visit a very unusual egg-laying site on a hydrothermal vent...

Thresher Sharks: The Biomechanics of Tail-Whipping with Jamie Knaub

Thresher sharks are known for their unusual hunting strategy. They use their long tail like a whip, striking it so fast that it creates a shockwave capable of stunning multiple fish at once! But how does their anatomy support such an extreme movement? In today’s episode we find out! We talk with Jamie Knaub, who researches the biomechanics and vertebral anatomy in large, swimming animals - including whales and sharks. In this episode we explore Jamie's research, including her most recent work studying the vertebrae of the thresher shark to understand how they are able to carry out that iconic tail whip. This episode has it all: the Olympians of the shark world, surprise humpbacks, sharks with anxiety, digital dissections and of course some deliciously nerdy science.

Protecting sharks and coastal livelihoods with Dr Hollie Booth

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.

Could climate change affect baby sharks? With Noémie Coulon

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.

The mystery of Charlotte, the pregnant stingray with Dr David Shiffman

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! 

You can find out more about David here https://davidshiffmancv.com/, find his book here https://www.press.jhu.edu/books/title/12267/why-sharks-matter and read his article on Charlotte for Southern Fried Science: https://www.southernfriedscience.com/no-a-shark-did-not-get-a-stingray-pregnant-but-what-really-happened-is-pretty-cool/

Tackling the fin trade with CITES with Luke Warwick

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...
