Hooded and Venomous: Exploring the Diverse World of Cobras.AnhDiep

Cobras, a species of venomous snakes often found in the Elapidae family, are known for their ability to expand their neck ribs, forming a distinct hood. However, it’s important to note that not all snakes referred to as Cobras belong to the same genus or family. The name “Cobra” is derived from the Portuguese term “Cobra-de-Capelo,” meaning “snake with a hood” or “hood-snake.”

When these snakes feel threatened, they have a characteristic behavior of rearing up and spreading their necks as a display of intimidation. Among the various types of Cobras, the Spitting Cobra possesses a unique defensive capability. When defending themselves against predators, they can eject venom from their fangs. The venom, harmless to intact skin, can cause permanent blindness if it enters the eye and is left untreated, leading to chemosis and corneal swelling. The venom is expelled in distinct geometric patterns through muscular contractions of the venom glands, which force the venom out through forward-facing holes at the fang tips. Some species of Spitting Cobras can project their venom up to a distance of 2 meters (6.6 feet) when cornered. While spitting venom is their primary defense mechanism, all Spitting Cobras are also capable of delivering venom through a bite.

Most species of Cobras have venom that exhibits significant hemotoxic effects, in addition to the neurotoxic effects commonly associated with other Cobra species. While Cobras rarely attack humans without provocation, they unleash their deadly bites when disturbed, making full use of their venomous capabilities.
