Cobra pronunciation is a venomous snake belonging to the family Elapidae. However, not all snakes commonly referred to as cobras are of the same genus, or even of the same family. The name is short for cobra capo or capa Snake, which is Portuguese for "snake with hood", or "hood-snake" When disturbed, most of these snakes can rear up and spread their necks (or hoods) in a characteristic threat display.
The king cobra (Ophiophagus hannah) is the world's longest venomous snake, with a length up to 5.6 m (18.5 ft). This species, which preys chiefly on other snakes, is found predominantly in forests from India through Southeast Asia to the Philippines and Indonesia. Despite the word "cobra" in its name, this snake is not a member of Naja ("true cobras") but belongs to its own genus.
