海豹”打手” Harp Seal, Gulf of Saint Lawrence, Canada

在加拿大的圣勞倫斯海灣，一頭年輕的海豹正在它的冰窩里警惕的東張西望。斷奶后褪去一身絨毛的海豹被稱為打手，因其總是在水上拍打它們的鰭狀肢。它們的一身光順完好的毛皮，是海豹獵人們的首要目標。

A young fur seal looks warily around an icy whelping site in Canada’s Gulf of St. Lawrence. Seals that are weaned and have shed their downy fur are called beaters for the way they beat their flippers on the water. Their sleek, unmarred pelts are prime quarry for seal hunters.

西印度海牛 West Indian Manatee, Florida

海牛可長達13英尺(4米)，重達1,300磅(600公斤)。與其它許多動物一樣，海牛的體型掩蓋了它們在水中的優雅。它們常在沿岸的水中以每小時5到15英里(每小時8到24公里)的速度優雅的滑水。北弗羅里達的泉水常年保持72華氏度(22攝氏度)的恒溫，西印度海牛常去那片水域過冬.

Like many creatures, the manatee’s bulk-they can be as much as 13 feet (4 meters) long and 1,300 pounds (600 kilograms)-belies its aquatic grace. Also called sea cows, manatees are graceful swimmers that typically glide along coastal waters at 5 to 15 miles an hour (8 to 24 kilometers an hour). This West Indian manatee is wintering in a North Florida spring, attracted by the region’s constant 72 degrees Fahrenheit (22 degrees Celsius) waters.
非洲獵豹 Silhouette of African Cheetahs, Africa

這張惹人注目的剪影照片顯現出一頭走向一棵樹準備午后小憩的獵豹的矯健的身影。獵豹是陸地上速度最快的動物，曾在亞非大地上大量生長，但它們的幼獸常為獅子等捕食，棲息場所也因不斷增加的農莊和牧場而縮減。如今在自然資源保護者的幫助下，估計約有12,000只獵豹遍布在30個國家里。

A striking silhouette shows off the lithe form of a cheetah approaching a tree for a late afternoon slumber. The fastest land animal in the world, cheetahs once thrived in Africa and Asia, but lion predation haunts their young, and farms and ranching have reduced their habitat. Today an estimated 12,000 cheetahs live in 30 countries, helped by conservationists.
