California forest scorpion

Uroctonus mordax

無害對人無害。不用擔心。

螫吃：肉

The California forest scorpion is a small scorpion that lives in the Redwood Forests and Oak Woodlands of California. Scientists consider it a foundational species, meaning many other living things in these forests depend on it. It is shy and rarely seen.1

毒液力量

螫

毒液從螫針出來。

牠的毒液有什麼作用？

It is venomous. Its sting is milder than a honeybee's sting.1

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。

It is described as smaller than a little finger, with a sting milder than a honeybee's. It is so shy that it is most often seen running away.1

牠害怕時會做什麼？

It is most often seen running away rather than standing its ground.1

如果牠螫人

用冰敷袋冰敷螫傷處，讓傷者保持不動。趕快就醫，特別是小朋友：有些蠍子對小孩是致命的。

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。
如果被牠螫了：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

牠有多快？

值得知道

小知識

It is so shy that it hunts only on moonless nights.1

After birth, the young climb onto the mother's back, and their legs never touch the ground during the climb.1

It is considered a foundational species in California's Redwood Forests and Oak Woodlands, which means the ecosystem relies on it.1

It needs a moister environment than many other scorpion species, so it stays under rocks, bark and dead trees.1
