哪種動物有千里眼？──湯瑪斯‧W‧克羅寧

動物王國裡的動物有許多不同種類的眼睛。有些眼睛可以個別旋轉，有些眼睛有波浪狀的瞳孔。有些眼睛具有保護性的眼皮，有些眼睛則會噴血。但哪種生物的視力最好？在黑暗中誰看得最清楚？誰能看得最詳細？誰能看到最多種顏色？最後，誰又能最快偵測到動靜？湯瑪斯‧W‧克羅寧解答了這些問題。

In the animal kingdom, eyes come in a dazzling variety, each adapted for a specific visual feat. Colossal squids have soccer-ball-sized eyes to sense faint light in the deep, while birds of prey like peregrine falcons spot rabbits from over three kilometers away. Bluebottle butterflies can see with at least 15 types of photoreceptors, and flies process visual motion ten times faster than humans. Each animal’s vision excels in its own way, but no single eye dominates every category.
