Boxer crab anemone
The boxer crab anemone is a small sea anemone, only about 1.5 cm tall, that lives on reefs in the warm Indo-Pacific. It is the only species in its genus, and it is special because it teams up with small boxer crabs, which carry it in their claws.1

怎样认出它
- Small and pale brown, with a base about 1 cm across1
- A crown of about 50 relatively long tentacles on top1
- A ring of branching, pale brown pseudo-tentacles halfway up the body1
- Grey, pink or green bulges called vesicles on the pseudo-tentacles1
- In daylight its pseudo-tentacles look dark brown, because of the algae they contain1
毒液之力
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, called cnidocytes, are packed into the vesicles and tentacles. The venom is strong enough to stun small prey. In the Red Sea it is reported to be one of the most venomous sea anemones, and the toxic agent is very stable, resisting chemicals and heat.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。In the Red Sea it is reported to be one of the most venomous sea anemones. Stings to bare skin cause pain and swelling.1
它害怕时会做什么?
Its vesicles, which are well armed with stinging cells, protect the pseudo-tentacles, which might otherwise look like food to a predator.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。

- 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

事实
Boxer crabs of the genus Lybia hold one of these anemones in each claw and wave it like a weapon to keep predators away.1
If a crab loses one anemone, it can tear the other in half, and each half grows into a new individual.1
The crab uses its anemones to stun and catch prey for itself.1
In one reported case, a sting left skin pain and swelling for several weeks, with a dark, blistered mark and long-lasting sensitivity.1
The anemones seem unharmed by being carried and used in this way.1
