The ring's large size means that it was able to see in darkness.

巩膜宽大意味着它能在黑暗中视物。

The researchers also found that Shuvuuia had a very wide scleral ring -- tiny bones that circle the eyeball.

研人员还发现鸟面龙有非常宽的巩膜——绕眼球的微小骨骼。

Most of it is that white stuff called the sclera, while the most anterior part is the transparent cornea.

大部分是被称为巩膜的白色物质，而最前面的部分是透的角膜。

In fact, research has shown that our surprisingly white scleras, the area that borders the iris, isn't just an accident.

事实上，研我们那如此洁白的巩膜, 也就是虹膜边境的西，并非是个巧合。

Recycling of that heme group yields unconjugated bilirubin, which at high concentration can cause scleral icterus, jaundice, and bilirubin gall stones.

亚铁血红素的循会产生非结合胆红素，其浓度过高会导致巩膜黄染、黄疸与胆红素胆结石。

I know icteric sclera, yellow eyes and yellow baby.

我知道黄疸巩膜，黄色眼睛和黄色婴儿。

In 2010, a group of researchers looked at a sample of eye bones, called scleral rings.

2010年，一组研人员研了一组被称为巩膜的眼骨样本。

One interesting byproduct is that humans have relatively large white sclera and nearly black pupils and a dark iris.

一个有趣的副产品是，人类拥有相对较大的白色巩膜、近乎黑色的瞳孔以及深色的虹膜。

And along with the scleral rings, researchers have unearthed more fossil evidence that dinosaurs weren't entirely limited to daytime hours.

而且，除了巩膜，研人员还发现了更多化石证据，恐龙并非完全局限于白天活动。

The sclera covers everywhere except the very front of your eyeball, where it connects to the clear tissue that makes up your cornea.

巩膜覆盖了眼球除了最前面的部分，那里它连接到构成角膜的透组织。

The whiteness you see when you look at your eye is the sclera the outer layer that holds the whole sac of goo together.

当你看向你的眼睛时看到的白色部分是巩膜，它是外层组织，将整个眼球紧紧包裹在一起。

It's so important that even dogs have evolved to have larger white sclera and more developed eyebrow muscles in order to show more of their sclera.

正因如此重要，狗甚至进化出了更大的白色巩膜和更发达的眉肌，以便展示更多巩膜。

You don't see such prominent white sclera in any other primates, which means that the importance of nonverbal expressiveness and intent is especially important for human survival.

在其他灵长类动物中， 你看不到如此显著的白色巩膜，这意味着非语言达和意图的重要性对于人类生存尤为关键。

Now, some dinosaurs also had scleral rings, and when they applied that same approach to 23 dinosaur fossils in 2011, the researchers found that plenty of them were most likely active at night—including hunters like Velociraptor.

现在，一些恐龙也具有巩膜，研人员在2011年对23具恐龙化石应相同方法时发现， 其中很多很可能在夜间活动， 包括像迅猛龙这样的猎食者。
