Monocled cobra; Adrian spectacled cobra; Spitting cobra; King cobra; Egyptian cobra. They are all hooded and extremely venomous.

Anti-venom
King cobras are stronger that the tarantula by far. The cobra is a reptile that can get upwards in length of 18'.

So my most educated guess would have the king cobra winning.
They don't make a shelter, but live in trees.
