海豹 seal [英][si:l] [美][sil] 中英文对照：海豹和海狮 海豹可以下潜到1000英尺深海，可以在水下停留30分钟。比较任何其他的动物，相对于他们自己的身体尺寸，他们有更多的血液。他们是陆地的同时也是冰面的伴侣。一个海豹身体里有四十五到百分之五十的脂肪。正因为如此，一些小海豹体重极其快速的增加，几乎每天可以增加重量3磅，直到大约三周的时候断奶后才稍微打住。灰海豹的学名来自希腊语，意思是“钩鼻海豚。” 而海狮可以下潜到475英尺深的海里，能在水下停留20分钟的时间。 Seals are able to dive 1000 feet and can stay underwater for 30 minutes. They have more blood for their body size than any other land animal. They come on land or ice to mate. A seal's milk is forty-five to fifty percent fat. Because of this, some seals grow extremely fast adding almost three pounds a day until they are weaned around three weeks of age. The grey seal's scientific name Halichoerus grypus comes from the Greek and means "hook-nosed sea pig." Sea lions can dive up to 475 feet deep and can stay under water for 20 minutes at a time. |
