Habu jellyfish
會螫人的觸手The habu jellyfish is a species of box jellyfish. It lives in coastal waters around Japan, including Okinawa and the Ryukyu Islands, and in the Philippines. It was discovered in 2009, and it is highly venomous.1

怎麼認出牠
- The bell is box-shaped.1
- Adults have a smooth bell. Juveniles have a warty bell.1
- Typical adults are about 60 mm tall. The largest recorded bell is about 110 mm tall.1
- Four short stalks, called pedalia, each carry tentacles. On average each stalk has seven tentacles, with up to nine.1
- The nematocyst threads, the stinging parts of the tentacles, are lavender.1
常被誤認為: It was once thought to be the same species as Chiropsalmus quadrigatus, found in Malaysia. That name is no longer recognised as a separate species. It is also closely related to Chironex fleckeri, but it is much smaller, with fewer tentacles on average.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?
The venom is highly potent. Its stings cause great pain. The symptoms include cardiac arrest, which stops the heart, and respiratory failure with acute pulmonary oedema, which means fluid builds up in the lungs and breathing fails.1
牠對人有多危險?
對人的危險: 非常危險如果沒有治療,牠可能會害死一個人。It is highly venomous and has caused several deaths in Japanese waters.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
Each of its four rhopalia, the sense organs at the bell edge, has six eyes. Two of these eyes have lenses.1
It has eight different types of stinging cells.1
Its adult bell is smooth, but juvenile bells are warty.1
Its maximum bell height is only one half to one third of the size of Chironex fleckeri.1
破解迷思
迷思: It is called the hub jellyfish.
真相: The name "hub jellyfish" comes from erroneous machine translations. Its Japanese name, habu-kurage, means viper jellyfish.1
