毒液之力

它的毒液会造成什么？

Its venom contains highly lethal neurotoxins for mammals, which are toxins that attack the nervous system. The venom attacks sodium and potassium channels, which are the gates that control electrical signals in nerves and muscles. In severe cases, this can stop the respiratory system and the heart from working. Two peptide toxins (small protein-based toxins) have been identified in the venom: noxiustoxin and Cn2 toxin.1

它对人有多危险？
