The Cape Cobra (Naja nivea) has a powerful venom and is one of the deadliest snakes in Southern Africa. Cape Cobras grow to an average of around 4 feet. Cape Cobras are particularly dangerous because they tend to be nervous and aggressive. Without treatment, the mortality rate in humans is 60% and death normally occurs 2-5 hours after being bitten, usually as a result of respiratory failure due to the onset of paralysis. The Cape Cobra is a beautiful looking snake some are yellow, some copper/mahogany colored and some are purplish/black. The Cape Cobra loves to hunt for rodents and can climb trees to raid weaver bird colonies. The Cape Cobra is common throughout dry regions in Southern Africa.
