美国国家地理图片精选·动物篇（二）

    原文：Bats in Cueva de Villa Luz, Mexico, 2001Photograph by Stephen Alvarez

    Bats emerge from the inky depths of Cueva de Villa Luz in southern Mexico. Hydrogen sulfide, which is poisonous to humans, permeates the caves walls, streams, and air, sustaining a rich variety of bizarre organisms. In addition to bats, spiders, mites, amblypygids, and small, hemoglobin-rich fish thrive in the sulfur-saturated environment.
