World of Sharks

What did prehistoric sharks look like? With Emma Bernard

What did the oceans look like 450 million years ago? Who were the weird and whacky ancestors of the sharks we know today? And could megalodon still exist? This week we're going back in time to answer all these questions and more at the Natural History Museum in London, with curator of fossil fish Emma Bernard!

Orca predation on white sharks with Alison Towner

What happens when two top ocean predators collide? This was a question that PhD candidate and white shark expert Alison Towner was faced with six years ago, when the subjects of her thesis started to wash up on shore with unusual, but fatal, injuries. Fast forward to 2022 and Alison has just led her second publication on the predation of white sharks by orca in South Africa, a behaviour that has never been documented until now. In this episode we chat to Alison about her findings, why we think orca are only now starting to show interest in white sharks, and the potential effects of predation by orca on not just white sharks as a species, but the entire ecosystem…

How can art help shark conservation? With Rachel Brooks

Could microplastics impact sharks? With Dr Alina Wieczorek

Whale and basking sharks are some of the biggest fish in the ocean – but could these gentle giants be threatened by something so small it can’t even be seen with the naked eye? We pitch this question to microplastics and pelagic fish expert Dr Alina Wieczorek. Alina has studied microplastic pathways from the smallest to the largest creatures in the ocean, and in some of the deepest and most remote places in the world. She has some really interesting, and at times deeply concerning, insights for us, but also a message of hope.

We discuss the mysterious life history of the whale shark, how climate change and fishing pressure might affect them, and how to conduct an ultrasound on a 30-foot shark while swimming alongside it...

Do sharks have friends? With Dr Bryan Keller

Welcome to another episode of The Whole Tooth, a shark podcast that asks YOUR questions to experts in shark and ocean science! This week, we are asking SOSF project leader and Science and Policy advisor for Saving the Blue, Dr Bryan Keller, all about shark social behaviour. Are sharks the lone wolves they’re always made out to be? Why do we sometimes see sharks in groups? And do they have preferences for who they hang out with? Diversions include some pretty cool encounters with sawfish - shark midwifery, anyone? - and, a first for this podcast, Love At First Sight...

Celebrating ocean wins! With Sarah Fowler OBE

We all know that our oceans are in trouble, and that taking action to protect and fight for them is incredibly important. But it can also be hard to motivate yourself to keep going, especially when it feels like change isn’t happening. But we are slowly turning the tide – and that is what this episode is all about. In honour of World Ocean’s Day (June 8^th), host Isla sits down with Sarah Fowler OBE, scientific advisor to SOSF and founding trustee of The Shark Trust, to discuss some the actions YOU are taking to help save our seas, and talk about how they are contributing to a positive impact worldwide.
