Bluebottle

Physalia utriculus

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 bluebottle is a floating sea creature that looks like a jellyfish, but it is actually a colony of many linked animals that work together. It drifts on the surface of warm oceans and often washes up on beaches in large numbers. Its long tentacle can cause painful stings, so it is important to know what it looks like.1

分布在

Indian, Atlantic and Pacific Oceans; the most common species on Australian coasts; also Hawaiian waters1

太平洋, 印度洋, 大西洋, 南冰洋, 珊瑚海, 南極洲, 帝汶海與阿拉弗拉海, 孟加拉灣

It floats on the surface of the sea, carried by currents, tides and wind. It is often stranded on beaches, where it can stay dangerous for weeks or months while the surrounding sand is moist. Most stings happen on beaches, especially on Australia's east coast.1

牠吃什麼？

It uses its long tentacle to detect and catch prey. The tentacle drags the prey towards the feeding parts of the colony, where it is digested.1

怎麼認出牠

A gas-filled float that sits on the surface, with a sail on top of it1
A single long tentacle hanging below the float1
A float about 16 cm across, smaller than the Atlantic Portuguese man o' war, whose float is about 30 cm1
Often found in large groups called swarms1
Often washed up in large numbers on beaches after strong winds1

常被誤認為： The Atlantic Portuguese man o' war (Physalia physalis) is closely related and looks similar. It has a larger float, about 30 cm across, while the bluebottle's float is about 16 cm. The bluebottle has a single long fishing tentacle.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 tentacle is covered in venomous cells called cnidocytes, which fire stinging threads called nematocysts. These toxic stinging cells cause painful injuries when they touch human skin. The stings can cause painful injuries at the beach.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。

On Australia's east coast, 10,000 to 30,000 stings per year from animals of the genus Physalia are reported, and most incidents happen on the eastern coast. No deaths have been recorded from stings by this species. The Atlantic Portuguese man o' war has caused at least three deaths.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

Bluebottle 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)

Bluebottle 大約 1 km/h (0,62 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 is not a single animal. It is a colony of four separate types of polyps and medusoids that work together.1

Its stinging cells can remain harmful on beaches for weeks or months if the sand stays moist.1

It moves across the sea using the wind, currents and tides, helped by the sail on top of its float.1
