Fried egg jellyfish

Cotylorhiza tuberculata

無害對人無害。不用擔心。

會螫人的觸手吃：每樣都來一點

The fried egg jellyfish is a jellyfish that lives in the Mediterranean, Aegean and Adriatic Seas. It gets its name from its flat, rounded body, which looks like a fried egg. Its sting has little or no effect on most people, so it is more of a nuisance than a danger.1

牠吃什麼？

It eats tiny drifting organisms, mostly a mix of phytoplankton (plant-like plankton) and zooplankton (animal plankton). It takes them in through its mouth arms, which carry the food to its stomach.1

怎麼認出牠

A smooth, raised central dome sits inside a gutter-like ring.1
The marginal lappets, the flaps around the edge of the bell, are long and roughly rectangular.1
Each mouth arm splits near its base and branches several times.1
Many short, club-shaped appendages with disc-like ends surround the mouth arms.1
Adults can reach 40 cm across, but are usually less than 17 cm wide. Older jellyfish lose colour and their bodies become damaged.1

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。

牠對人有多危險？

對人的危險: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

Its sting has very little or no effect on humans. However, it can cause allergic reactions in more sensitive people, usually itching and scratching in the stung area. Large summer blooms mainly cause problems for tourism and fishing.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？

Fried egg jellyfish 跟「你」比起來有多大？

牠有多快？

一隻花園蝸牛 大約 0,05 km/h (0,03 mph)

Fried egg jellyfish 大約 0,8 km/h (0,5 mph)

一個正在游泳的人 大約 3 km/h (1,9 mph)

值得知道

小知識

It has algae living inside its body, which use sunlight to make energy that the jellyfish can use and store.1

Researchers have studied its effects on certain breast cancer cells, though much more work is still needed.1

Its young cannot develop properly without these algae, as the algae help start the early stage of adult form.1

Its mouth arms carry sperm to females, which fertilise the eggs inside them.1

Its population grows into large blooms every summer, and it has a yearly life cycle.1

破解迷思

迷思： The fried egg jellyfish is dangerous to people because it stings.

真相： Its sting has very little or no effect on most people. Only sensitive people may react, usually with itching.1
