Cobras are venomous snakes of family Elapidae and include Taipans, Brown Snakes, Fierce Snakes, Coral Snakes, Mambas, and Sea Snakes. Elapidae cannot fold their fangs down as vipers can, so the fangs are generally shorter. They generally inhabit tropical and desert regions of Asia and Africa. Cobras kill their prey, usually small rodents and birds, by injecting a neurotoxin through their hollow fangs. The neurotoxin blocks the synaptic communication between the victim's neurons and muscles, thus stopping movement and control. The King Cobra notably eats other snakes and feeds almost entirely on other snakes, even venomous ones. The spitting Cobra can also incapacitate larger would-be predators by delivering venom to their eyes. Cobras come in varying colors from black or dark brown to yellowish white. The cobra's most recognizable feature is its hood, a flap of skin and muscle behind the head which it can flare, perhaps for the purpose of making it appear bigger and more threatening to predators. The Cobra's predators include the mongoose and some raptors.
