Australian spotted jellyfish

Phyllorhiza punctata

无害对人无害。不用担心。

会蜇人的触手吃：小小的海洋食物

The Australian spotted jellyfish is a jellyfish with a bell up to 50 cm wide. It is native to the western Pacific, from Australia to Japan, but has spread to many other seas. Its sting is mild and it is not considered a threat to people, but large groups can cause problems for fishing and local sea life.1

游泳, 粗略估计

它吃什么？

It feeds mainly on zooplankton, which it catches by filtering seawater. Fluid flows over clusters of tiny mouthlets near the base of its oral arm disk, and it must keep swimming to move food to the mouthlets for digestion.1

怎样认出它

Its name comes from its spotted pattern, and it is also called the white-spotted or brown jellyfish.1
The bell can grow up to 50 cm across.1
It usually travels in large groups.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？

It has only a mild venom. The venom is not strong enough to kill its prey, which is why it catches food by filtering rather than by stunning it.1

它对人有多危险？

对人的危险: 轻微像被蜜蜂蜇一下或更轻。对人基本无害。

It is not considered a threat to humans, and its sting is mild or hard to notice. It does cause harm to fishing industries, where it eats fish, crab and shrimp eggs and larvae and clogs nets.1

如果它蜇人

The sting can be treated with a dilute acid, usually white or cider vinegar.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

Each jellyfish can filter as much as 50,000 litres of seawater per day.1

One individual found on Sunset Beach, North Carolina, in October 2007 measured 74 cm wide, perhaps the largest ever recorded.1

Large swarms can clog fishing nets, damage boat intakes and sometimes force fishing areas to close.1

Its polyps can multiply by dividing into other polyps, which makes a larger group than the one the mother started with.1

Its polyp stage can last up to five years, and its adult stage up to two years.1

In the Gulf of Mexico, medusae grow unusually large, reaching more than 60 cm across.1

谣言粉碎机

谣言： It is a dangerous jellyfish that is a serious threat to people.

真相： It has only a mild venom and is not considered a threat to humans. Its main harm is to fishing and the local ecosystem, where it eats large amounts of zooplankton.1
