Fatness is not unique to us humans. There are plenty of supersized animals out there. 肥胖不仅人类的面临的问题，许多动物也意外的受其困扰。 But determining which animal is the fattest isn’t as straightforward as it may appear. 但是准确说出哪一个动物是最胖，并不像表面上看着那么容易。 But if we look at things proportionally, you might be surprised by some of the world’s full-fat species. 但是仅仅看脂肪比例的话，你就会惊叹这个世界上竟然还有体脂含量百分之百的动物。 We’ll begin with blubber, the fat rich tissue belonging to marine mammals that has myriad benefits for streamlining, buoyancy, defence, insulation and energy storage. 先来说一说海兽脂，海洋生物的脂肪组织统称为海兽脂。它在塑造流线体型、漂浮、防御、保暖、储存能量方面起到了巨大的作用。 Right whales Among the whales with the thickest blubber are the so-called right whales. They are popularly thought to have earned this common moniker during the bloody era of whale hunting in the 19th Century. 拥有最厚海兽脂的鲸鱼称之为所谓的“露脊鲸”——这个公认的绰号源于血腥的十九世纪，那时候鲸鱼遭到人们的捕杀。 “They are slow and fat and when harpooned they float for easier retrieval. Most other whales sink.” says Dr Sam Ridgway, president of the National Marine Mammal Foundation.The whales float because they have a high percentage of lipids, or fat, in their blubber. There are three species of right whale, found in the North Atlantic, North Pacific and Southern Oceans. |
