The Notojima strain is the largest L rotifer used by Japanese fish farmers.

日本养鱼户使用最大L轮品种是三岛品种。

Bdelloid rotifers, meanwhile, have been reproducing parthenogenetically for 60 million years.

与此同时，蛭形轮已经孤雌生殖了近 6000 万年。

If you wanna get small, there's rotifers and other kinds of...protozoans.

如果你想要小一，有轮和其他种类......原生动物。

So this little rotifer shows us something really amazing.

这小小轮展示了一种神奇可能。

For the smallest fry these are often rotifers, a phylum of tiny animals discovered in the late 17th century by early microscopists.

最小鱼苗通常会喂食轮，轮是17世纪晚期由早期显微镜学家发现一门微小动物。

It means that a successful mutated line of rotifers will not be diluted by the genetic mixing caused by sexual congress.

这意味着一个成功轮突变系不会被有性繁殖引起基因混合所。

You remember the rotifer we just met?

你记得我们刚认识轮吗？

Just a reminder, rotifers have a simple brain and a simple nervous system.

提醒一下，轮有一个简单大脑和一个简单神经系统。

And in one sample collected in 2015, the researchers found this one little rotifer.

霍普金：在 2015 年收集一个样本中，研究人员发现了这种小轮。

Paul McEuen: So this little rotifer shows us something really amazing.

Paul McEuen：所以这个小轮向我们展示了一些非常惊人东西。

So, the previous record for frozen rotifers was a decade or so.

霍普金：所以，冷冻轮先前记录是十年左右。

While it was stuck to Heliozoa's axopodia, this rotifer actually lays its egg.

当它粘在日光动物轴足上时，这种轮实际上会产卵。

But neither egg nor the rotifer is going to escape this.

但是鸡蛋和轮都无法逃脱这一。

In fact, these little ladies reproduce asexually, laying eggs that hatch into the next generation of self-propagating rotifers.

霍普金：事实上，这些小雌性进行无性繁殖，产卵孵化出下一代自繁殖轮。

In this video, a rotifer has been captured by a Heliozoa and it is slowly getting eaten by it.

在这段视频中，一只轮被日光动物捕获并慢慢被它吃掉。

Now, the fact that rotifers can spring to life after a thaw is not a total surprise.

现在，轮在解冻后能够重新活过来这一事实并不完全令人惊讶。

First Paradileptus immobilizes the rotifer with fired toxicysts and the animal is swallowed by the single-celled organism as it swims away.

首先，Paradileptus 用发射毒囊固定住轮，当它游走时，轮被单细胞生物吞噬。

The next step is studying how rotifers can chill for millennia and still maintain their cellular integrity.

霍普金：下一步是研究轮如何在寒冷几千年后仍然保持其细胞完整性。

That's why we are going to study proteins that help rotifers to survive in those conditions.

Malavin：这就是为什么我们要研究有助于轮在这些条件下生存蛋白质。

It's a microscopic worm called a rotifer that was brought back to life after spending about 25,000 years locked in the arctic permafrost.

这是一种被称为轮微型蠕，在被困在北极永久冻土层中大约 25,000 年后复活了。
