Purple-striped jelly
The purple-striped jelly is a jellyfish with a bell marked by purple stripes. It lives off the coast of California, and scientists study it closely because so little is known about how it feeds. Its sting is extremely painful to people, though stings are rare.1

怎麼認出牠
- The bell can be up to 70 cm across and usually has a radial pattern of purple stripes.1
- Juveniles are pinkish, with long, dark maroon tentacles.1
- Adults have eight long, dark marginal arms and four frilly oral arms.1
- As it ages, the tentacles thicken and look pale, and the oral arms become harder to see.1
毒液力量
有東西碰到時,成千上萬個小小的刺細胞就會發射。
牠的毒液有什麼作用?
Its stings release stingers that paralyse prey. Its sting is extremely painful to humans.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。The sting is extremely painful to humans, but stings are rare.1
如果牠螫人
- 離開水裡,把觸手拿掉(戴手套或用布)。
- 熱帶箱形水母:在螫傷處倒醋至少 30 秒,求救,並準備好做心肺復甦術(CPR)。藍瓶水母和大多數其他水母:用海水沖洗,再用熱水止痛。
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

小知識
Young Cancer crabs make their home in the jellyfish and eat the parasitic amphipods that feed on it and damage it.1
Leatherback turtles are the main predator of this jellyfish, which they favour because its four oral arms are rich in carbon and nitrogen.1
A specimen about 15 feet (4.5 m) long has been reported.1
It is more active in lively currents, which helps it move and catch prey.1
