十种透明动物 10 Transparent Animals

This bizarre deep-water fish called the Barreleye (Macropinna microstoma) has a transparent head and tubular eyes. It has extremely light-sensitive eyes that can rotate within his transparent, fluid-filled shield on its head, while the fish's tubular eyes, well inside the head, are capped by bright green lenses. The eyes point upward (as shown here) when the fish is looking for food overhead. They point forward when the fish is feeding. The two spots above the fish's mouth are not eyes: those are olfactory organs called nares, which are analogous to human nostrils. 

这种怪异的深海鱼被称之为“Barreleye”(学名大鳍后肛鱼)，长着一个透明的脑袋和管状的眼睛。Barreleye的眼睛对光线极为敏感，并且能够在鱼头上充满液体的透明防护体内旋转，它的管状眼睛长在头内，被亮绿色的晶体盖住。如图所示，当搜寻头顶上方的食物时，Barreleye的眼睛就会指向上方；摄食的时候，眼睛就会指向前方。鱼嘴上方的两个小点可绝不是眼睛，而是嗅觉器官鼻孔，与人类的鼻孔类似。
