The Spitting Cobras

Saturday, October 31st, 2009

The snake called the spitting cobra is one of the most peculiar species as it not only has a venomous bite but it also sprays venom into the eyes of its prey and aggressors. Contact of this venom with your eyes can be very painful and even temporarily blinding, therefore, if you get cobra venom in your eyes, irrigate them immediately in order to prevent permanent tissue damage.

The King Cobra, Ophiophagus hannah, also distinguishes itself in this large family of snakes (elapids) by the fact that it feeds almost entirely on other snakes with mice and small birds also falling prey to its venom.

The King Cobra is also unique because of its size - it can reach 5.85m (almost 20 feet) in length, which makes it the longest poisonous snake in the world. The latest discovery of a new species of cobra was made in 2003 when it was identified by London Zoo as part of an illegal shipment of exotic pets.

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’.

Although they are highly dangerous when threatened cobras will rarely attack if you keep your distance from them, although the spit can travel very accurately for two meters. Compared to the strike of a rattlesnake, the cobra is rather slow in its attack and besides that, many bites prove to be non-venomous.

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.

The colouration is variable from light green-grey to black, while juveniles are yellow and black banded. This snake can find a habitat all over south-eastern Asia.

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.
