咬伤

它咬的时候，毒液通过毒牙或牙齿出来。

它的毒液会造成什么？

Its venom contains many neurotoxins, which are poisons that affect the nerves. They mainly act on sodium and calcium ion channels, which are the gates that let charged particles move in and out of nerve and muscle cells. The venom also contains enzymes, including serine proteases, metalloproteases, cholinesterases and hyaluronidases, which may explain some of the effects of a bite.1

它对人有多危险？

对人的危险: 严重被咬了要去看医生。死亡非常罕见。

Most recorded human bites caused mild to moderate symptoms. All the recorded bites were from adult spiders. One bite caused severe symptoms, including kidney failure (renal failure).1

如果它咬人

清洗咬伤处，用冰袋冷敷止痛。如果疼得厉害、疼痛扩散或感到不适，就去看医生。

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它咬了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

值得了解

事实

Each egg sac can hold up to 1300 eggs, which is far more than most spiders produce.1

Adult females can have a stride length of more than 10 centimetres.1

Spiderlings become adults only after 14 to 17 moults.1

Sexual maturity is reached 300 to 465 days after the spiderlings leave the egg sac.1

It prefers disturbed land, such as areas changed by people, rather than deep undisturbed forest.1
