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。
