[27] [28] However, because of its large venom glands and specialized fangs, the western diamondback rattlesnake can deliver a large amount of venom in a single bite. The average venom yield per bite is usually between 250 and 350 mg, with a maximum of 700–800 mg. [ 5 ] [ 29 ] Severe envenomation is rare but possible, and can be lethal.
