The Teddy Bear Cholla cactus has the ultimate protection - a fuzzy coating of vicious spines, and Sir David Attenborough found out the hard way when filming The Green Planet for BBC One. The swollen, water-filled buds fall off the young plants when something brushes against it. The creators decided to test this on The Green Planet, and whilst wearing two sets of safety gloves Sir David still managed to feel the prick of the cactus’s spikes.
