蝙蝠(光明洞) Bats in Cueva de Villa Luz, Mexico

位于墨西哥南部的露滋村的光明洞(Cueva de Villa Luz)中，蝙蝠出現在漆黑的洞穴深處。洞穴的石壁，水流和空氣中充滿了對人體有毒害的硫化氫，供養了多種奇特的生物。除了蝙蝠之外，這個硫磺飽和的環境下還孳生著大量的蜘蛛，螨蟲，有鞭蝎以及一種富含血紅蛋白的小魚。

Bats emerge from the inky depths of Cueva de Villa Luz in southern Mexico. Hydrogen sulfide, which is poisonous to humans, permeates the cave’s 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.
打哈欠的老虎 Yawning Tiger, India

如圖中這只印度班達迦國家公園的雌老虎，在炎熱的天氣里老虎總是沒精打采的打瞌睡，以為夜里的捕獵積蓄能量。在最近的一百多年里，捕殺以及森林的破壞使得老虎的數量由幾十萬只驟減到不到2,500只。如今，班達迦據稱保持著國內最高的老虎密度。

Over the last hundred years, hunting and forest destruction have reduced tiger populations from hundreds of thousands of animals to perhaps fewer than 2,500. Today Bandhavgarh claims to maintain the highest density of tigers in the country.
