They are a very fast snake and can be difficult to catch, I've never had one actually try to bite me while tailing but pin their head and they'll bite every time. Their venom will cause localised pain and a lot of swelling, lymph glands will cop a beating and be painful as well, with probable nausea and a general feeling of sickness. Like all snakes they are very quick to run away, this one is in the middle of its shed cycle and obviously will be feeling very vulnerable. Id rate their venom as more mid range then low toxicity, and would take a venom fuelled bite from one of these as serious enough.
