它吃什么？

It feeds on prey by pushing out its proboscis, a tube-like feeding organ. It has a cluster of sticky filaments at the end of the proboscis that it uses to immobilise its prey.1

怎样认出它

毒力

皮肤里有毒

它的皮肤有毒。摸、舔或吃都很危险。

它的毒会造成什么？

The bootlace worm does not bite or sting, so it is poisonous rather than venomous. Its mucus contains a relatively strong neurotoxin, which attacks the nerves. The mucus is highly toxic, but tests showed low toxicity in human cells.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。

No human injuries or deaths from this worm are known. Its mucus is highly toxic, so it is best not to touch it.1

它害怕时会做什么？

When handled, it releases large amounts of thick, toxic mucus, which it uses to deter predators.1

如果有人碰了或吃了它

把伤口泡在热水里，水温以不烫伤为限、尽量热，然后去看医生取出刺。不要自己去挖。

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。
如果你碰了或吃了它：不要揉眼睛或嘴巴，洗手并就医。

它不是冲着你来的。它的毒只是为了不被吃掉。更多安全知识

值得了解

事实

In 1864, a specimen more than 55 metres long washed ashore after a severe storm near St Andrews, Scotland. It was longer than the lion's mane jellyfish.1

The bootlace worm is one of the longest known animals, and individuals have been recorded at up to 30 metres.1

Its mucus kills crabs and cockroaches in tests, and it could be used as an agricultural insecticide.1

Its body is very flexible and can stretch far beyond its usual length.1

谣言粉碎机

谣言： The bootlace worm regularly grows to over 55 metres long.

真相： Reports of worms over 55 metres may be animals that were stretched. Ribbon worm bodies are flexible, so measurements should be treated with caution. Individuals are known to reach up to 30 metres.1
