怎麼認出牠

  • Dark brown on top, with yellow-orange bristles on the abdomen (opistosome).1
  • The underside is dark brown with four rows of light yellow spots.1
  • Body length up to 3.5 cm, with a leg span of up to 14 cm.1
  • Males have an orange band running lengthways down the middle of the body.1
  • Females have dark brown jaws (cheliceras) with yellow bristles.1

常被誤認為: It is very similar in appearance to Phoneutria fera and Phoneutria reidyi. The key difference is the anterior flat lobe: it is convex here, much more distinct in P. fera, and poorly developed in P. reidyi.1

牠害怕時會做什麼?

如果牠咬人

  • 清洗咬傷處,用冰敷袋冰敷止痛。如果很痛、疼痛擴散或傷者覺得不舒服,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
