From Wikipedia, the free encyclopedia
Keep in mind that venom toxicity veries from region to region; even whithin the same species, Naja haje (Egyptian cobra) is generally considered LESS toxi than Naja naja (Indian cobra). Ld-50 for an Egyptian cobra is 1.15 mg/kg. compared to 0.45 mg/kg. for an Indian cobra. Also, the Forest cobra, I believe is the largest of najas, at least in Africa. It is not known if Cleopatra even used a snake to commit suicide but if she did, Naja haje is the likely candidate, although, I'm not too sure it would have been painless. Many cobra bites although highly nuerotoxic, are quite painfull!--Todg 17:21, 1 September 2006 (UTC)
