A tarantula is orange and black because it was originated like that. The Tarantula mostly lives in Australia. The Tarantula is probally as big as a 9-10 year old's hand. When you ask, why the tarantula is orange and black, it is because God decided to design a tarantula orange and black. I don't know if that answer is true, but I think I might as well think positive. Just be careful what you step on when you go to Australia. If might as well be a Tarantula. :0
