cobra


A cobra (About this sound pronunciation) is a venomous snake belonging to the family elapidae. The name is short for cobra de capelo, which is Portuguese for "snake with hood", or "hood-snake".[1] When disturbed, most of these snakes can rear up and spread their neck (or hood) in a characteristic threat display. However, not all snakes referred to as cobras are of the same genus, or even of the same family.
