Barney Harwood and Gemma Hunt introduce a host of wonderful and wacky wildlife - from the furry to the freaky and the bold to the beautiful. What's more, they're all connected by some fabulous facts! It's back to school for Barney and Gemma - physics with the electrifying electric eels, geography with the monarch butterflies and a gentoo penguin PE class, all make this a lesson with a difference at Latin America High School!
