The Greenbottle Blue Tarantula (Chromatopelma cyaneopubescens), a native of the Paraguaná peninsula, Venezuela, has some of the most dramatic coloring of any spider species. Adult greenbottles have metallic blue legs, a blue-green carapace and a vibrant orange abdomen. They are very active, fast-growing and particularly attractive to tarantula hobbyists.
I'd run a mile away if I saw that a lightyear away... anyway, nephila komaci is the largest spider known, females sometimes have 2 feet legs and, yes, they kill the males. They live in southern Africa around Madagascar all the way through South Africa.
P. metallica is a species of tarantula. It reflects brilliant metallic blue color. This whole genus of arboreal tarantulas exhibits an intricate fractal-like pattern on the abdomen. The spider's natural habitat is primarily Southeastern India and Sri Lanka. P. metallica was first discovered in a town in central southern India called Gooty. Hence, its common name is Gooty Sapphire Ornamental Tree Spider, or simply Gooty Sapphire.
