This habitable area is known as the photic zone.

这片适宜居住地带被称为光带。

In its current state, only certain parts of the oceans are considered to be in the photic zone.

在目前情况下，在海中，只有特定一些区域光带。

But if the oceans were to be completely transparent, theoretically, every part of the sea would be a photic zone.

但如果海，那么就理论上而言，海每一部分就都会光带。

The photic zone, which is bathed in sunlight during the day, and starlight and moonlight at night, reaches down a few hundred metres.

光层白天沐浴在阳光之中，夜晚沐浴星光和月光，光层低达几百米。

The so-called photic sneeze reflex, AKA the Autosomal Cholinergic Helio-Ophthalmic Outburst, abbreviated" ACHOO" … yes, seriously… is experienced by about 1 in 4 people, leading scientists to believe it is genetically heritable.

所谓“强光喷嚏反射”，又称常染色体胆碱能性赫里奥眼突出症，简称“Achoo”… ，讲真… 大约有四分之一人经历过，这使得科学家相认为它会遗传。
