Giant Caribbean sea anemone

Condylactis gigantea

无害对人无害。不用担心。

会蜇人的触手吃：肉

The giant Caribbean sea anemone is a large, colourful sea animal that looks like a soft, flower-shaped blob on the seabed. It lives in shallow reefs and calm inshore waters in the Caribbean and western Atlantic. Its sting is strong enough to stun the fish and shrimp it eats.1

生活在

Caribbean Sea and West Indies, and the western Atlantic from southern Florida through the Florida Keys; also common in Bermuda1

It is usually found in crevices in rock walls, or attached to a rock, shell or other hard object in shallow water with full-strength seawater most of the time. It is very common around reefs, in both forereef and lagoon areas.1

它吃什么？

It eats fish, mussels, shrimp, zooplankton and sea worms. Its stinging cells paralyse the prey, which is then carried to the mouth and swallowed whole.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 stinging cells (nematocysts) at the tentacle tips contain a toxin called CgNa. When the stinging cells fire, they impale the attacker and release the toxin, which causes extreme pain and paralysis.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。

它害怕时会做什么？

When threatened it shrinks by pulling its tentacles into its body and forcing out most of the water, which reduces the surface a predator can attack.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

Its nerve cells contain proteins that are molecularly similar to those in mammal nerve cells, which helps scientists study how nervous systems evolved.1

Fish and cleaner shrimp shelter among its tentacles, and it serves as a base station for fish cleaning.1

Although mostly stuck in place, it can crawl very slowly on its base, the pedal disc.1

Its larvae carry their own food in a yolk, so starvation is unlikely and they can drift far to spread out.1

Most individuals are either male or female, with a roughly equal ratio of the two sexes, though they occasionally have both.1
