These barbed structures, known as nematocysts, are released on contact.

这些尖锐的结构叫做刺丝囊，会在接触时释放。

Similarly, jellyfish package their venom safely in harpoon-like structures called nematocysts.

同样，水母将毒液安全地包裹在鱼叉状结构中，称为线虫囊。

And sea slugs eat jellyfish nematocysts, prevent their activation with compounds in their mucus, and repurpose them for their own defenses.

海蛞蝓吃水母线虫囊，用粘液中的化合物阻止线虫激活，并将它们重新用于自身防御。

Even if severed, the tentacle of a jellyfish can still be dangerous and will automatically fire off its stingers if unspent nematocysts come in contact with exposed skin.

即使被切断，水母的触手仍然很危险， 如果未用完的线虫囊接触到裸露的皮肤， 它会自动发射毒刺。

So with a simple neon tube, you're going to fish for jellies with a net, and using neoprene gloves to protect your skin, start gathering tentacles, which is where the nematocysts, or stingers, are located.

因此，使用简单的霓虹灯管，您将用网捕捞水母， 并使用氯丁橡胶手套保护您的皮肤， 开始收集触手，这是刺细胞或毒刺所在的位置。

The mucus could work like the coating on clownfish that helps them fend off the nematocysts of anemones, which might be a slimy physical barrier or have a chemical component to stop the cells from stinging in the first place.

粘液可以像小丑鱼身上的涂层一样起作用， 帮助它们抵御海葵的线虫囊，这可能是一种黏糊糊的物理屏障， 或者含有一种化学成分， 可以从一开始就阻止细胞刺痛。
