Cobra Snakes

Decent Essays

Snakes are fun to know about. They are scary, poisonous createars that killed many people. And cobras are one of the most famous snakes (Cleopatra used an Egyptian cobra to kill herself). So, I choose cobras to make a research on.
Cobras
Cobras are venomous snakes of family Elapidae, of several genera. They generally inhabit tropical and desert regions of Asia and Africa. Cobras kill their prey, usually small rodents and birds, by injecting a neurotoxin through their hollow fangs. The King Cobra notably eats other snakes; it feeds almost entirely on other snakes, even venomous ones (ophiophagy). The spitting cobra can also incapacitate larger would-be predators by delivering irritating venom to their eyes. Cobras come in varying colors …show more content…

However, there was a clear difference in the traces left by the two species: whereas the black-necked cobra sprayed its venom, the attack by the red Mozambique cobra is reminiscent of something shot from a double-barrelled water pistol.

What is decisive for the high degree of accuracy is a pattern of behaviour which researchers were able to observe in both species. "In super slow motion it is clearly visible that the snakes move their heads rapidly when squirting the toxin," Dr. Westhoff explains. "Rather like we do when we wish to use a garden hosepipe to water the flowers of an entire flowerbed." In this way the venom is spread out over a larger area; the chance that it will hit one eye increases.
However, Dr. Westhoff would like to scotch one prejudice: "Cobras only spit when they feel threatened, not to kill their prey," he says; "anything else is a myth." They kill their prey like other poisonous snakes do, by biting them and thereby injecting the venom into their bloodstream, which then proves fatal. Human beings are not on their list of potential prey; even so, these snakes are dangerous – even when they are
