毒液力量

會螫人的觸手

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 stinging cells release a venom made of complex, toxic proteins. Stings can cause itching, swelling, acute pain, redness and inflammation. Some stings damage muscle tissue, causing swelling and, in some cases, death of the muscle.1

牠對人有多危險?

對人的危險: 嚴重被螫了需要看醫生。死亡案例非常罕見。

Severe stings are becoming more common. In severe cases, stings can cause death.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

牠有多大?

牠有多長?

Nomura's jellyfish 大約 2 m 長 (6,6 ft)大人的腳踏車 大約 1,8 m (5,9 ft)一台汽車 大約 4,5 m (15 ft)

牠有多重?

跟 10 隻狗一樣重
跟 4 隻家貓從鼻子接到尾巴一樣長跟 11 根香蕉頭尾相接一樣長可以在 78 秒內游完一座大游泳池(50 公尺)

Nomura's jellyfish 跟「你」比起來有多大?

小知識

1

In 2009, a fishing trawler capsized off Chiba while its three crew were hauling in a net full of these jellyfish. Another trawler rescued all three.1

2

It can grow from the size of a grain of rice to more than 1.8 m wide in about six months.1

3

Its venom is being studied for possible medical uses. In cancer research, the venom has been shown to slow a process that helps cancer cells spread.1

4

It is one of the largest jellyfish ever recorded, in the same size class as the lion's mane jellyfish.1

5

Blooms have grown more frequent since the 20th century, with the largest recorded between 2002 and 2003.1
