The aptly-named king cobra is the largest venomous snake in the world, reaching lengths of about 5 meters (about 18 feet). When disturbed, it raises its hooded head to get a better view or to strike. Large individuals may raise themselves to a height of about 1 meter (about 4 feet). They are aggressive if harassed, and their bite is deadly. They prey chiefly on other snakes and frequent bamboo thickets, forest clearings, mangrove swamps, and other densely vegetated habitats. Females may construct a nest chamber in which eggs are laid-the only snake known to do so. The species, Ophiophagus hannah, is native to South and Southeast Asia.
