Cobra snake

A is a venomous snake, which is a member of the family Elapidae (elapids). The name is short for cobra de capelo, which is Portuguese for "snake with hood," or "hood-snake." 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.
Cobra may refer to any member of the genus Naja, also known as typical cobras (with the characteristic ability to raise the front quarters of their bodies off the ground and flatten their necks in a threatening gesture), a group of venomous elapids found in Africa and Asia.
