I love looking for giant earthworms on rainy days. It’s always exciting to see their long squirming bodies underfoot – and the big ones are always a treat to find. Well, trust David Attenborough to find a worm that trumps all others when it comes to body size. These Australian monsters can be up to 6 feet long! Imagine the network of massive slithery beasts that exists beneath the soil in this very unique part of the world. This is the stuff of horror movies!
