The Complex Web of Symbiosis

Enjoy a walk in Devon with Sophie Pavelle and discover the most unexpected relationships in the animal kingdom. In her new book, To Have or to Hold, Sophie explores why some species work together, while others exploit host animals as parasites. It's a fascinating world full of surprises – and even horrors.

Plodcast host Fergus joins Sophie for a meander along the River Otter – with a cast of wildlife turning up along the way.
