Rainforests are some of the planet's oldest and most established ecosystems. They are full of hairy things, stripy things, smelly things and scary things. More than a third of Earth's animals and two thirds of all the known plant species are found in these sopping wet habitats. Armstrong Wedgewood (Matt Lucas) reveals the astonishing diversity of creatures found in forests across the world, from the diminutive pygmy gecko to the cute, goggle-eyed tarsier.
