Are narwhals the closest creature to unicorns that we can ever know? How does the Greenland shark fill its 500 years on our planet? Is the iridescent golden mole a mole or an elephant? On this episode of the podcast we're joined by award-winning author and academic Katherine Rundell. In conversation with environmental historian and broadcaster Eleanor Rosamund Barraclough, they discuss the individual strangeness and beauty of the animal kingdom and the fragility of our natural world. — We’d love to hear your feedback and what you think we should talk about next, who we should have on and what our future debates should be about.
