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

在加拿大的圣劳伦斯海湾，一头年轻的海豹正在它的冰窝里警惕的东张西望。断奶后褪去一身绒毛的海豹被称为打手，因其总是在水上拍打它们的鳍状肢。它们的一身光顺完好的毛皮，是海豹猎人们的首要目标。

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

海牛可长达13英尺(4米)，重达1,300磅(600公斤)。与其它许多动物一样，海牛的体型掩盖了它们在水中的优雅。它们常在沿岸的水中以每小时5到15英里(每小时8到24公里)的速度优雅的滑水。北弗罗里达的泉水常年保持72华氏度(22摄氏度)的恒温，西印度海牛常去那片水域过冬.

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.
非洲猎豹 Silhouette of African Cheetahs, Africa

这张惹人注目的剪影照片显现出一头走向一棵树准备午后小憩的猎豹的矫健的身影。猎豹是陆地上速度最快的动物，曾在亚非大地上大量生长，但它们的幼兽常为狮子等捕食，栖息场所也因不断增加的农庄和牧场而缩减。如今在自然资源保护者的帮助下，估计约有12,000只猎豹遍布在30个国家里。

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.
