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

与此同时，蛭形已经孤雌生殖了近 6000 万年。

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

如果你想要小一点，还有和其他种类......原生动物。

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，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.

这意味着一个成功突变系不会被有性繁殖引起基因混合所稀释。

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

提醒一下，有一个简单大脑和一个简单神经系统。

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

霍普金：所，先前记录是十年左右。

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。

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

现在，在解后能够重新活过来这一事实并不完全令人惊讶。

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

霍普金：下一步是研究如何在寒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在这些条件下生存蛋白质。

Entering a state of cryptobiosis allows even modern rotifers to survive seasonal changes in their local environment and more otherworldly assaults.

进入隐生状态甚至可让现代在当地环境季节性变化和更多来自其他世界攻击中生存下来。

Above the size of L rotifers, however, farmers switch phylum and feed their charges crustaceans called brine shrimps, the smallest of which clock in at 400 microns.

然而，L号再往上，农民们换了门，用一种被称为“盐水虾”甲壳类动物喂食，最小盐水虾长度有400微米。

Rotifers are better—or at least more interesting—because they're multicellular animals, with a head and a body, that can eat, crawl around and make more rotifers.

霍普金：更好——或者至少更有趣——因为它们是多细胞动物，有头部和身体， 可进食、爬行并制造更多。
