它吃什么？

It feeds mainly on zooplankton (tiny animals drifting in the water), especially mollusc veligers, copepods and their nauplii. It uses stinging cells on its arms to immobilise prey.1

怎样认出它

Colour ranges from light blue to dark blue or purple.1
Large, rounded bell, about 25 to 30 cm across.1
The bell pulses in a rapid, staccato rhythm.1
Found along the Eastern Australian coast, often in large numbers.1

常被误认为： Two forms are recognised on the Eastern Australian coast. Catostylus mosaicus mosaicus, found in New South Wales and southern Queensland, has small or no papillae (small projections) and a larger bell. Catostylus mosaicus conservitus, found in the Bass Strait, has clear papillae, is blue or white, and has a smaller bell.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 arms carry stinging cells and can produce a mild but irritating sting. The sting is described as mild, and no further effects on the body are described.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。

Its sting is described as mild but irritating. The main problem is the large blooms, which can interrupt recreation in coastal areas.1

它害怕时会做什么？

Its stinging cells on the arms are used to defend it from threats.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

事实

Its stinging venom is being studied for possible anticancer effects against lung cancer cells in laboratory research.1

It is harvested for food and is considered a delicacy in some countries, including China and Japan.1

A small copepod lives on its oral arms and is thought to feed on mucus the jellyfish produces.1

Blooms can be very dense, and they can take food away from other animals such as fish.1

Sea turtles and jellyfish-eating fish, including tuna, butterfish, sunfish and spiny dogfish, prey on it.1

It has a partnership with photosynthetic algae, though it has less of these algae than many other jellyfish.1

排序: Rhizostomeae
大洲: 印度洋, 太平洋, 珊瑚海, 海洋
宝宝: Fertilised eggs develop into free-swimming planula larvae, which settle on the seabed and grow into a polyp stage. The polyp then produces young jellyfish (ephyrae), which mature into the free-swimming medusa.1
