It is usually found in warm, open seas, but it sometimes appears inshore in large numbers. Large numbers have washed up on beaches after gales, and dead jellyfish have been seen floating on the surface after heavy rain.1

怎样认出它

Cube-shaped and colourless, so it is clear and hard to see in the water1
Bell about 14 cm across, with a flat top and rounded top edges1
Four lower corners, each with a bundle of 7 to 9 tentacles1
Outer two tentacles are pinkish, inner ones yellowish white1
Tentacles can be up to 3 to 4 metres long1

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？

The stinging cells on the tentacles release venom that causes an extremely painful sting. The sting is linear, meaning it leaves a line of marks on the skin. Apart from pain, it can cause heart dysfunction and slowed breathing, which are systemic symptoms that affect the whole body. The rash can last for several months.1

它对人有多危险？

对人的危险: 非常危险不治疗可能会害死人。

The sting is extremely painful and can be life-threatening. A four-year-old boy in the Gulf of Mexico died within forty minutes of being stung. Off the coast of Brazil, 16 stings over five years were identified as coming from this species. Children are especially at risk.1

好消息：医生有药（抗毒血清）或治疗方法。1

它害怕时会做什么？

Its long, stinging tentacles deter predators.1

如果它蜇人

Antivenom given within a few hours of the sting relieves the pain somewhat, reduces the severity of the rash and improves other symptoms. In extreme cases, cardiopulmonary resuscitation (CPR) can be effective if started promptly.1
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

事实

Its bell is almost completely transparent, which makes it hard to spot in the water.1

Its tentacles are the longest part of its body, reaching several metres in length.1

Along the Texas Gulf coast in 1955 and 1956, large numbers appeared inshore during drought, when the water was saltier than normal.1

Scientists have done little research on this species, and studies have found that jellyfish from different regions can have different stinging cells.1

Small specimens were often caught in shrimp trawls, while the adults were seldom seen near the surface.1
