　　A blind, albino crayfish swims through the inky depths of Sims Sink in northern Florida. These colorless crustaceans are among the few creatures that have adapted to the lightless world at the bottom of the region’s aquifers, springs, and sinkholes. Many species who make their homes in these freshwater labyrinths are endemic to only a handful of aquifers and are found nowhere else in the world.

　　北弗罗里达Sims Sink漆黑的深水里，一只晶莹剔透的盲眼小龙虾正在游动。在这个无光的世界中，只有深海含水层与落水洞，犹如坠入淡水迷宫一般。这些甲壳类动物是少数几种能适应此种环境的物种，它们属于地区性生物，仅存在于少数含水层中，在世界上的其他地方都未曾发现。
