英文閱讀測驗轉學考題part4

Gray seals have a surprising way to make their air last longer: " deferred food-processing. " The marine mammals can stay submerged 20 minutes without coming up for a breath, gulping down as many fish as they can stomach. Most animals start digesting their food as soon as they eat it. But digestion uses oxygen, a precious commodity for an animal holding its breath. Gray seals can put off digestion until after they stop hunting and return to land --- sometimes hours later --- according to new research from the University of St. Andrews in Scotland. This ability may let seals forage longer and in deeper water.
