November 7th, 2009The Spitting Cobras
The spitting cobra is one of the most peculiar species of snake as it not only has a deadly bite but it also sprays venom into the eyes of prey and aggressors alike. Contact with the eyes can be very painful and even blinding, therefore, if you accidentally get cobra snake venom in your eyes, wash them out immediately so as to prevent permanent damage to the tissue.
The King Cobra (Ophiophagus hannah) is also remarkable in this large family of snakes (elapidae) because it feeds almost entirely on other snakes with mice and small birds also falling prey to its poison.
The King Cobra is also a record-holder because of its size – it can reach almost twenty feet (585 cms) in length, which makes it the largest poisonous snake in the world. The most recent discovery of a new species of cobra was made in 2003 as part of an illegal shipment of exotic pets at London Zoo.
DNA studies revealed that this new species of snake is similar to the red spitting cobra but has different genes. It seems to originate from an area between Sudan and Egypt and it has been called the ‘Nubian Spitting Cobra’.
Though highly dangerous when it senses a threat, a cobra will not attack if you leave it in peace, although the venomous spit can travel very accurately for two meters. If compared to the strike of a rattlesnake, the cobra is pretty slow in attack, and many bites prove blank, that is without envenomation.
According to a study conducted on Malaysian cobra snake victims only 55% of the bites involved venom release and the same statistics indicate a mortality rate of 10% for people bitten, since the toxins injected into the blood of the prey destroy the nerves (neurotoxin) , which induces respiratory failure half an hour after being bitten, giving you 30 minutes to get help.
Their colouration varies from light green-grey to black, although juveniles are yellow and black banded.This snake is widespread throughout south-eastern Asia.
