Mediterranean box jellyfish

Carybdea marsupialis

只是會痛不要碰會痛，但不會對你造成嚴重傷害。

會螫人的觸手吃：肉

The Mediterranean box jellyfish is a small, see-through jellyfish with a box-shaped body about 3 cm across. It lives only in the Mediterranean Sea, where it is the only box jellyfish, and its sting can hurt people who swim in shallow water.1

It lives in the upper few metres of the open sea and often moves through shallow water. Swimmers in the Mediterranean are the people most likely to meet it.1

長度

牠吃什麼？

It eats invertebrates and even small fish. It catches prey with stinging cells, called nematocysts, on its tentacles, often in shallow waters.1

怎麼認出牠

Transparent, box-shaped bell about 3 cm across1
Four long tentacles at the lower corners of the bell, up to 30 cm long1
Red banding on the tentacles1
Small white or yellowish warts on the bell that carry stinging cells1
Often found in small groups1

常被誤認為： Other box jellyfish of the genus Carybdea look similar, but they live in warm oceans elsewhere. The red banding on the tentacles is the feature that separates this species from them.1

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 sting is venomous to humans, but some swimmers feel no painful sensation at all. In severe cases the symptoms spread through the body, with pain at the sting site and elsewhere, paresthesia (abnormal prickling or tingling sensations), hyperesthesia (over-sensitive skin) and skin lesions. These symptoms can take a few months to fully disappear.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。

It is far less dangerous than some box jellyfish species from other parts of the world. It is still considered the second-most significant stinging jellyfish in the Mediterranean, after Pelagia noctiluca.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？

大約跟一根迴紋針一樣長可以在 36 秒內游完一座大游泳池（50 公尺）

Mediterranean box jellyfish 跟「你」比起來有多大？

只是在你的瀏覽器裡做算術。什麼都不會儲存，也不會傳送到任何地方。

牠有多快？

一個正在游泳的人 大約 3 km/h (1,9 mph)

Mediterranean box jellyfish 大約 5 km/h (3,1 mph)

奧運游泳選手 大約 8 km/h (5 mph)

小知識

It has comparatively sophisticated eyes with lenses, which help it detect and avoid obstacles such as posts or a ship's rudder.1

After a free-swimming larva forms, it develops into a polyp that can reproduce by budding, and it can regenerate missing parts within 72 hours.1

It swims by making rapid contractions of its bell, moving between 3 and 6 metres per minute.1

Its tentacles can grow up to 30 cm long, many times the width of its box-shaped bell.1

It is the only box jellyfish found in the Mediterranean Sea.1

學名: Carybdea marsupialis
類群: 水母和會螫人的海洋生物
家人: Carybdeidae2
排序: Carybdeida
各大洲: 大西洋, 地中海, 海洋
寶寶: The sexes are separate, and eggs and sperm (gametes) are released into the open water to fuse; the young develop into a free-swimming larva and then a small polyp stage before becoming jellyfish.1
