Bluebottle

Physalia utriculus

只是会疼不要触摸会疼，但不会对你造成严重伤害。

会蜇人的触手吃：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

生活在

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

首页

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

它吃什么？

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

怎样认出它

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

常被误认为： 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

毒液之力

会蜇人的触手

一碰到东西，成千上万个小刺细胞就会发射。

它的毒液会造成什么？

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

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

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

如果它蜇人

离开水面，取下所有触手（戴手套或用布）。
热带箱水母：在蜇伤处倒醋至少 30 秒，呼救，并准备好做心肺复苏。僧帽水母和大多数其他水母：先用海水冲洗，再用热水止痛。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它蜇了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

值得了解

事实

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
