无害对人无害。不用担心。
水母和海中蜇人生物 会蜇人的触手吃：肉
对人的危险: 轻微像被蜜蜂蜇一下或更轻。对人基本无害。

The spotted jelly is a jellyfish with spots on the top of its bell, the rounded body. It lives in the warm Indo-Pacific oceans, and in some saltwater lakes in Palau and Indonesia. Its lake populations are famous because they have lost most of their sting.1

首页
Lives in the open ocean across the Indo-Pacific, and in marine lakes, which are saltwater lakes cut off from the sea. Some Palau populations gather in huge groups called smacks, which are tourist attractions. The best-known spot is Ongeim'l Tketau Lake in Palau, also called Jellyfish Lake.1

它吃什么？
Feeds on zooplankton and other tiny organisms, which it catches with its stinging cells. It also gets much of its nutrition from photosynthetic algae called zooxanthellae that live inside its tissues.1

怎样认出它

  • Distinctive spots on the top of the bell1
  • Colour ranges from greenish blue to olive green, from the algae living in its tissues1
  • Eight rhopalia (sensory organs) along the edge of the bell1
  • Eight frilled oral arms, each ending in a club-like appendage1
  • Numerous small mouths along the bottom of the oral arms, unlike many other jellies1

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 venom is protein-based and is delivered by stinging cells called nematocytes (cnidocytes) on the upper surfaces of the oral arms. In jellyfish living in marine lakes, conditions in the lake are thought to break down this venom, so those populations do not sting humans.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。

Jellyfish in the open ocean have stinging cells on their oral arms. Populations in marine lakes, such as Jellyfish Lake in Palau, do not sting humans.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

1

Lake populations of spotted jellies have lost most of their ability to sting, probably after being cut off in marine lakes long ago.1

2

Each day, spotted jellies rise to the surface and follow the sun from east to west, so their algae can photosynthesise.1

3

Lake jellyfish are over three times wider than ocean ones, yet their tentacles are about the same length.1

4

Unlike many jellies, spotted jellies have several small mouths along their oral arms.1

5

A sea anemone called Entacmaea medusivora preys on spotted jellies, catching them in its tentacles.1

6

At night they stay lower in the water column.1

谣言粉碎机

谣言： All spotted jellies sting people.

真相： Ocean populations have stinging cells, but the jellyfish in marine lakes such as Jellyfish Lake in Palau do not sting humans.1
