Hollywood has a lot to answer for when it comes to how we view sharks. The Great White, we all know. But sharks have been around since before the dinosaurs, and in that time they've evolved into 538 different species of all different shapes and sizes - and counting. Sharks with glow-in-the-dark armpits, sharks that can fit in your pocket, sharks with spots, sharks with frills. Isla Hodgson joins Hannah in the studio, and she's got some astonishing shark facts up her sleeve.

Also - you'll meet Shaama Sandooyea, a climate activist from Mauritius who staged the world's first ever underwater climate protest.
