Cobra

Cobras are venomous snakes known for spreading the neck ribs to form a hood. Many live in Africa or Asia and feed on mammals, birds, reptiles or other animals. The hood is a defensive display, accompanied in some species by raised posture or hissing. Some cobras can project venom toward a threat, but this ability is not shared by every species. Their habitats range from forest and wetland to dry country and farmland. The common name includes several snakes with different scientific relationships.
