Beadlet anemone

Actinia equina

無害對人無害。不用擔心。

會螫人的觸手

The beadlet anemone is a small sea animal that lives fixed to rocks on the shore. It looks like a blob of jelly when the tide is out, but under water it opens a crown of tentacles. It is common around the coasts of northern and western Europe, the Mediterranean, Africa, Australia and East Asia.1

It lives on rocky shores in the intertidal zone, the part of the shore covered by the sea at high tide and exposed at low tide. It can be found in both exposed and sheltered spots, and in places where salt levels vary, such as estuaries.1

怎麼認出牠

Under water, it has up to 192 tentacles arranged in six circles.1
Out of water, the tentacles pull in and it looks like a blob of red, brown, green or orange jelly.1
It is up to about 5 cm across.1
It has bright blue beads just beneath the tentacles, at the top of its body.1

常被誤認為： The Waratah anemone of Australia and New Zealand has a similar form. The strawberry anemone is also similar, but the beadlet anemone is a single uniform colour and is usually smaller.1

會螫人的觸手

有東西碰到時，成千上萬個小小的刺細胞就會發射。

牠對人有多危險？

對人的危險: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

牠害怕時會做什麼？

It uses its blue beads, which contain stinging cells, to fight other anemones over territory, and it pulls its tentacles in when out of water.1

如果牠螫人

離開水裡，把觸手拿掉（戴手套或用布）。
熱帶箱形水母：在螫傷處倒醋至少 30 秒，求救，並準備好做心肺復甦術（CPR）。藍瓶水母和大多數其他水母：用海水沖洗，再用熱水止痛。

一定要先打緊急電話（112、000、911）。這是一般急救指引，不是醫療建議。急救基本知識

注意安全

絕對不要碰、抓或捉弄野生動物，就算是很小的動物，就算牠看起來在睡覺或已經死了也一樣。
給牠空間。如果遇到了，保持冷靜，慢慢往後退，讓牠自己離開。
如果被牠螫了：保持冷靜，保持不動，打緊急電話（112、000、911）或趕快去醫院。記住牠的樣子，有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己，而且牠更想躲起來。更多安全知識

小知識

A famous individual called "Granny" was found on Scotland's east coast in 1828 and produced several hundred offspring before it died in 1887.1

The only known predator of the beadlet anemone is the grey sea slug.1

They can tolerate high temperatures and drying out, which helps them survive on the shore.1

Beadlet anemones can live alone or in clusters, and solitary ones tend to grow larger.1
