Puff adder
Oh goody, the Puff adder, or the Bitis arietans, is responsible for the most fatalities over any other African snake. This is mainly due to the fact that it has wide distribution, a large size, potent venom produced in really large amounts, long fangs, and the habit of basking by footpaths while sitting quietly when it is approached. Ugh, sounds horrible!
Black-necked spitting cobra
Also known as the Naja nigricollis and it is found mainly in Sub-Saharan Africa. This particular bunch has medically significant venom, although the mortality rate of untreated bites to humans is relatively low (although that doesn’t really fill me with a lot of warm, fuzzy feelings). Again, as with the other spitting cobras, the Black-necked spitting cobra also releases a venomous poison most dangerous to the skin and yes.
