Moon jellyfish

Aurelia aurita

无害对人无害。不用担心。

会蜇人的触手吃：肉

The moon jellyfish is a see-through jelly that drifts with the ocean currents. It lives in the north Atlantic, Argentina and parts of the northeastern United States. It is one of the best-known jellyfish, and it is not dangerous to people.1

首页

The young polyp stage lives on the seabed in estuaries, bays, fjords and even polluted waters. The adult jellyfish (medusa) swims and drifts in the water.1

它吃什么？

It catches medusae, plankton, copepods, molluscs and fish eggs with its short, fine tentacles. It then brings the food into its body to digest it.1

怎样认出它

Almost entirely translucent, so it looks nearly see-through1
Usually about 25 to 40 cm across1
Four horseshoe-shaped gonads (reproductive organs) are easy to see through the top of the bell1
Short, fine tentacles1

常被误认为： Most species in the genus Aurelia look very similar, and it is hard to tell them apart without genetic testing. Many older records of this jellyfish may actually describe one of its related species.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 sting has a mild effect on humans. Most people have little or no reaction to 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 dangerous to humans. Its sting is mild, and most people feel little or nothing.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

它有多大？

它有多长？

和 2 根香蕉首尾相接一样长和 12 块玩具积木排成一排一样长

Moon jellyfish和你比起来有多大？

只是在你的浏览器里算一算。什么都不会被保存或发送到任何地方。

它有多快？

一只花园蜗牛 约 0.05 公里/小时 (0.03 mph)

Moon jellyfish 约 0.9 公里/小时 (0.56 mph)

一个在游泳的人 约 3 公里/小时 (1.9 mph)

值得了解

事实

The moon jellyfish is almost entirely translucent, so it is hard to see in the water.1

Its polyp stage can survive for months without food.1

Its reproduction changes with food supply: plenty of food means many small young, while little food means fewer, larger young that are more likely to survive.1

Before the 2020s, the species was thought to live almost everywhere in the world, but it has since been split into at least 28 species.1

给毒液专家

学名: Aurelia aurita
类别: 水母和海中蜇人生物
家人: Ulmaridae2
排序: Semaeostomeae
大洲: 北冰洋, 大西洋, 太平洋, 印度洋, 南大洋, 地中海, 红海, 加勒比海, 墨西哥湾, 南海, 南极洲, 北海, 帝汶海和阿拉弗拉海, 孟加拉湾, 加利福尼亚湾, 海洋
宝宝: It reproduces sexually as a free-swimming medusa, while the polyp stage reproduces asexually. When food is plentiful, it produces many small offspring, and when food is scarce, it produces fewer, larger offspring that survive better.1
