Giant green anemone

Anthopleura xanthogrammica

无害对人无害。不用担心。

会蜇人的触手吃：肉

The giant green anemone is a sea animal that looks like a flower but is a relative of jellyfish. It lives on rocky and sandy shores along the Pacific coast of North America, where it is covered by water for most of the day. Its bright green colour comes partly from tiny algae that live inside its body and make food for it.1

怎样认出它

Bright green when underwater in good sunlight.1
Dark green or brown when out of the water, because it closes up and droops, showing its darker outer body.1
Broad, flat top surface (oral disk) with no stripes, bands or other markings.1
Short, cone-shaped tentacles arranged in six or more rows around the mouth, with pointed or blunt tips.1

常被误认为： Large giant green anemones can be confused with A. elegantissima or A. sola. Those two usually have pink-tipped tentacles and a striped oral disk, which the giant green anemone does not have.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？

Stinging cells called nematocysts in the tentacles release a paralysing venom that helps the anemone catch prey.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？

It uses its stinging cells in the tentacles to defend itself against predators.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。

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
