Japanese sea nettle
會螫人的觸手The Japanese sea nettle is a large jellyfish that lives in the northwest Pacific Ocean, including the waters around Japan, Korea, Taiwan and China. It has long, curtain-like arms and many tentacles, and its sting is strong enough to be dangerous to people.1

怎麼認出牠
- The bell is 15 to 21 cm across and divided into 8 sections.1
- The outer surface has 32 reddish stripes running from the centre to the edge.1
- Four oral arms hang from the centre of the bell and are 2 to 3 times as long as the bell is wide.1
- The oral arms are delicate and curtain-like, with fringed edges.1
- About 40 elastic tentacles line the edge of the bell.1
常被誤認為: The sea nettle was once confused with C. melanaster, which is larger and lives further north. Because of this, jellyfish kept in public aquariums have often been wrongly labelled as C. melanaster.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。Its sting is strong and can be dangerous to humans.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
If this jellyfish is injured, it rearranges the parts it still has to keep its body balanced, rather than growing back the parts it has lost.1
The bell's outer surface carries 32 reddish stripes that run from the centre outwards.1
Its 40 tentacles are elastic and grow to a length similar to its oral arms.1
