Hahn's six-eyed sand spider is a medium-to-large spider that lives in deserts and sandy places in southern Africa. It rests flat against the ground or under a little loose soil, and its velvety hairs let it blend in almost perfectly. Its bite can be medically significant, but people rarely come across it.1

It lives in sandy areas, usually under stones, buried in sand at the entrances of animal burrows, or at the base of rock overhangs and cliff faces. It is found in deserts, grassland, fynbos, Karoo and savanna. People are unlikely to meet it because it is reclusive and prefers untouched, open land.1

怎麼認出牠

  • Medium-to-large spider1
  • Body and legs covered in short, velvety hairs that pick up sand and dust, giving near-perfect camouflage1
  • Flattened body that sits low against the ground1
  • Three pairs of eyes, six in total1
  • Long, widely spaced legs1
  • Does not build a web1

毒液力量

咬

咬的時候，毒液會從毒牙或牙齒出來。

牠的毒液有什麼作用？

All Hexophthalma spiders produce venom with dermonecrotic effects, which means it can destroy skin and tissue. The damage is caused by proteins related to sphingomyelinase D, which are found in the venom of all sicariid spiders. For this species, the detailed effects on humans are unknown, because its venom has mainly been studied in the laboratory.1

牠對人有多危險？

對人的危險: 嚴重被咬了需要看醫生。死亡案例非常罕見。

The spider is capable of a medically significant bite. Serious or even life-threatening wounds are possible, especially if the wound becomes infected or the venom spreads through the body. No bites from this spider in southern Africa have been proven, and contact with people is considered unlikely.1

牠害怕時會做什麼？

It relies on stillness and camouflage rather than running, and it can shift quickly across loose sand when disturbed.1

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
