What is stronger than a king cobra snake?

King cobras are stronger that the tarantula by far. The cobra is a reptile that can get upwards in length of 18'. The Tarantula, and there are different species, is an arachnid that can get very large. The largest if the Goliath Bird-Eating Spider can reach a leg span of up to 12". So my most educated guess would have the king cobra winning.
