Red Island Birdeater Tarantulas are stunningly large terrestrial spiders. They are typically bronze-brown but can have a pinkish sheen after moulting. Red Island Birdeaters have a reputation for being skittish, ornery and defensive. These feisty tarantulas are good webbers and can grow up to 22cm in size. So if you are a tarantula enthusiast you must have to have one.
