Isn't cobra venom comprised mainly of neurotoxins?
Yes. Keyword: mainly. I feel pretty confident in saying that (nearly) all elapids have hemotoxins in their venom. Venoms are really a cocktail of toxins... some just have more of certain ones than others. Even though cobras arent known to have an extreme amount of hemo or cytotoxins, they can still have an affect on your tissue.
