Poecilotheria ornata

Poecilotheria ornata, along with P. rufilata is one of the largest pokeys and, in fact, one of the largest arboreals in the world. Like the other pokes, they are purported to have powerful venom compared to most other tarantulas. They are native to Sri Lanka (or India... not sure). They're lighning quick, and can be agressive. This combined with their painful bite makes them a poor choice for a beginner, but a stunning specimen for a more experienced keeper.

Thats scary! gorgeous but scary lol

Yes it is really very impressive and very unforeseeable !
