Twin-spotted rattlesnake
The twin-spotted rattlesnake is a small venomous snake that lives among rocky mountains in the south-western United States and northern Mexico. It is a pit viper, a group of snakes that use heat-sensing pits to find their prey. No bites to people from this snake have been recorded.1

怎麼認出牠

- A series of dark blotches runs along the back, often split down the middle to form 39 to 64 pairs1
- It is a small rattlesnake, usually 50 to 60 cm long including the tail1
- It has a rattle at the tail end1
毒液力量
咬的時候,毒液會從毒牙或牙齒出來。
牠的毒液有什麼作用?
Its venom is not well studied. Some have suggested it may be highly potent, but little is known about its effects on the body.1
牠對人有多危險?
對人的危險: 疼痛可能會非常痛,但幾乎從來不會很嚴重。No bites to humans from this snake have been recorded.1
牠害怕時會做什麼?
It may rattle furiously at people passing by, although the sound can be hard to hear among the rocks. Its colour pattern helps it blend with the light and shadow of the mountains.1
如果牠咬人
- 讓傷者保持不動和冷靜,讓被咬的手臂或腿保持在和心臟一樣的高度,取下戒指和緊身的東西,並趕快送醫院。
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
