The rinkhals is a close relative of the true cobras; it spreads a hood, ‘spits’ and has a pair of fangs fixed to the front of the upper jaw. Among other subtle features, the rinkhals differs (with a true cobra snake) by having keeled scales and by giving birth to live young.
Once you know which features to look out for there is no mistaking the rinkhals – if it is standing up and spreading a hood. When standing in defense the first feature you might notice are the pale cream to yellow bars on the throat area. There are usually between one and three although some individuals have four while some don’t have any.
Unlike the cape cobra, the rinkhals is generally much darker underneath and in the Western and Eastern Cape and Kwa-zulu Natal provinces it is usually strongly banded.
If the rinkhals is not standing its ground one might mistake the bands and stocky build of this snake for that of a puff adder, although the bands do not form the same chevron-like pattern.
Sometimes when one is looking out for a black back and yellow marking underneath one may mistake a male boomslang for a rinkhals, especially if you only see it for a second. The most noticable difference is that male boomslang would be yellow down the entire length of their underside whereas the rinkhals only has one to four crossbars.
Contrary to popular belief the rinkhals is by no means an aggressive snake.
In fact, the rinkhals will do virtually everything in its power to avoid a confrontation. It will hiss, spread a hood, ‘spit’ venom with incredible accuracy and convincingly sham death. Many people bitten by rinkhals make the mistake of picking up what they think to be a dead snake.
Leave all snakes alone, even dead ones! (just a friendly word of advice).
Bites rarely occur from the rinkhals and there is debate as to whether there as ever been a recorded fatality. That being said the neurotxic/ cytotoxic venom combination is potentially lethal and bites should be treated seriously.
