What makes it so unique from all other Snakes? King Cobra is the longest venomous snake on the planet. The King, or Hamadryad, as he is sometimes called, holds the record length of 24 feet for a Venomous snake. Bill Haast, the famous Snake and Venom expert who is a great friend of John Klein (founder of Cobras.org), once claimed he encountered a 35-feet King Cobra (!) during the 1960’s. The Hamadryad is also unique for the remarkable fact he is the only snake in the world that makes a nest for its eggs! He scraps up leaves and other debris in which to deposit them, and remains in the nest until the young hatch. Isn’t that remarkable?
