Tooth and Claw: Great White Sharks

Bbc World Service
About this episode

Adam Hart investigates the most famous and feared predator in all the ocean – the great white shark! With rows of large, serrated teeth, it’s often thought of as a ferocious man-eater and was the villain of the film Jaws – which frightened a generation of beachgoers. This star of the silver screen may be the subject of fascination and fright for many, but is it really the ultimate predator of the ocean as Hollywood has led us to believe?

Adam hears what it’s like to see these sharks up-close and in person for the very first time. He learns more about how great whites detect and hunt their prey, as well as the challenges they’ve been facing due to another ocean predator. Contributors:

Dr Alison Towner is a postdoctoral researcher at Rhodes University in South Africa. She has a PhD in white shark ecology and has been studying the displacement of great whites due to orcas (killer whales) in South Africa.

Professor Gavin Naylor is Director of the Florida Program for Shark Research. He is a biologist who has specialised in evolutionary and population genetics, focusing on sharks.
