毒液力量

咬

咬的時候，毒液會從毒牙或牙齒出來。

牠對人有多危險？

對人的危險: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

Bites are generally not a serious harm to humans, except in the case of an allergic reaction. Because the fangs are large, the puncture wound can be painful and can become infected if not treated properly.1

牠害怕時會做什麼？

When disturbed, it rises onto its hind legs, raises its front legs in a threatening pose, and kicks small, coarse urticating hairs from its abdomen towards the threat.1

如果牠咬人

Bite wounds should be treated properly to prevent secondary infection. Seek care if an allergic reaction occurs.1
清洗咬傷處並冷敷。如果很痛或傷者覺得不舒服，要就醫。

一定要先打緊急電話（112、000、911）。這是一般急救指引，不是醫療建議。急救基本知識

注意安全

絕對不要碰、抓或捉弄野生動物，就算是很小的動物，就算牠看起來在睡覺或已經死了也一樣。
給牠空間。如果遇到了，保持冷靜，慢慢往後退，讓牠自己離開。
如果被牠咬了：保持冷靜，保持不動，打緊急電話（112、000、911）或趕快去醫院。記住牠的樣子，有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己，而且牠更想躲起來。更多安全知識

值得知道

小知識

Narrow-mouthed toads have been seen sharing the tarantula's burrow. The toads gain protection from snakes and eat small invertebrates there, but they ignore newly hatched spiderlings.1

This species is the main prey of the tarantula hawk wasp (Pepsis grossa) in areas where the two overlap.1

Males travel looking for females, usually in the fall, and have been recorded travelling as far as 1.7 km.1

Newly hatched spiderlings often stay with their mother for several days before they disperse to build their own burrows.1

Males usually live little more than a year after they mature.1
