Can sharks adapt to changing seas? With David Sims and Freya Womersley

We're back! And we're kicking off season 2 by exploring our rapidly changing seas and the impacts of these changes on shark movements, distribution and behaviour with scientists David Sims and Freya Womersley. Both David and Freya work on the Global Shark Movement Project (https://www.globalsharkmovement.org/), which aims to collate data on pelagic shark movements from around the world and investigate the potential impacts of human activities on these movements. In this episode, we discuss the cumulative effects of rapidly decreasing oxygen levels and warming temperatures on the foraging behaviour of blue and mako sharks; how fisheries and climate change can overlap and place further pressure on shark populations; and whether species can adapt to an increasingly hostile marine environment.

Along the way we hear about the amazing healing capabilities of whale sharks, learn how satellite tagging works and what it's like to be emailed by a basking shark...

Follow David (@TheSimsLab) and Freya (@FreyaWomersley) for more jawsome insights into the life of pelagic sharks!
