I have four questions. The first one is how exactly does the toxicity of banded krait venom and the venom of the common krait compare? Second: What would be considered a usual maximum length for a banded krait? Ive heard some say 6 feet and Ive heard others say 9 feet. Third: Is the head of a banded krait bigger than that of a common krait? Fourth: If the deadlyness of a venomous snake was based on only the toxicity of the venom and the average amount of venom the snake would "inject" in most instances and not at all related the snakes temperment, would the common krait be more deadly than a taipan(disregarding the inland taipan)?
