Carybdea marsupialis

只是会疼不要触摸会疼，但不会对你造成严重伤害。

会蜇人的触手吃：肉

The Mediterranean box jellyfish is a small, see-through jellyfish with a box-shaped body about 3 cm across. It lives only in the Mediterranean Sea, where it is the only box jellyfish, and its sting can hurt people who swim in shallow water.1

它吃什么？

It eats invertebrates and even small fish. It catches prey with stinging cells, called nematocysts, on its tentacles, often in shallow waters.1

怎样认出它

Transparent, box-shaped bell about 3 cm across1
Four long tentacles at the lower corners of the bell, up to 30 cm long1
Red banding on the tentacles1
Small white or yellowish warts on the bell that carry stinging cells1
Often found in small groups1

常被误认为： Other box jellyfish of the genus Carybdea look similar, but they live in warm oceans elsewhere. The red banding on the tentacles is the feature that separates this species from them.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 is venomous to humans, but some swimmers feel no painful sensation at all. In severe cases the symptoms spread through the body, with pain at the sting site and elsewhere, paresthesia (abnormal prickling or tingling sensations), hyperesthesia (over-sensitive skin) and skin lesions. These symptoms can take a few months to fully disappear.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。

It is far less dangerous than some box jellyfish species from other parts of the world. It is still considered the second-most significant stinging jellyfish in the Mediterranean, after Pelagia noctiluca.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

It has comparatively sophisticated eyes with lenses, which help it detect and avoid obstacles such as posts or a ship's rudder.1

After a free-swimming larva forms, it develops into a polyp that can reproduce by budding, and it can regenerate missing parts within 72 hours.1

It swims by making rapid contractions of its bell, moving between 3 and 6 metres per minute.1

Its tentacles can grow up to 30 cm long, many times the width of its box-shaped bell.1

It is the only box jellyfish found in the Mediterranean Sea.1
