A bad tempered E. c. sochureki, showing why they're one of the deadliest snakes on earth. The noise they make is caused by rubbing their heavily keeled scales together (stridulation), and is an attempt to scare off predators, and to warn other animals of the presence. Ignore the warning signs and they won't hesitate to bite defensively, often injecting a lethal dose of their incredibly toxic venom. Leave them alone and they'll leave you alone.
