Tarantulas are amazing. Not only do they include the largest of all spiders, with some species reaching a legspan the size of a dinner plate, but they are arguably some of the most beautiful too. While famous for giants that inhabit the jungles of South America, some species barely grow larger than your thumb nail. Some species live on trees in damp forests while others live in self-constructed tubular burrows in the ground in some of the most inhospitable deserts. Some have special protective hairs on their bodies which cause extreme itching when they come into contact with the mucous membranes of potential predators, while others produce a hissing sound in self-defense.
