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

小知識
Its eyes have a tapetum lucidum, a reflective layer that shines back at a light source once lit.1
The tapeta may help the spider navigate by detecting the polarisation of light from the sky.1
The tapetum is shaped like a canoe and cannot form sharp images, so its exact benefit is uncertain.1
It was probably first carried from Europe to the Americas during periods of colonisation.1
