Amy and Emily speak to Martina Quaggiotto (University of Glasgow, UK) about the science behind an interactive e-learning presentation that she has developed called ‘How smart are fish’, and Lucy Hawkes (University of Exeter, UK) about the amazing physiology of birds. They also discuss: Do bears really hibernate? Can animals talk? And how an experiment involving frogs wearing trousers helped scientists learn about reproduction. You can access the e-learning presentation 'How smart are fish?' here.
