For example, to help their Arctic-dwelling pups pack on the blubber, hooded seal moms produce a milk with 15 times the fat of cow milk.

例如，为了给自己的北极幼崽足够的脂肪，冠海豹妈妈的乳液中的脂肪是奶牛奶液的15倍。

Well, for hooded seal pups, that's nothing.

好吧, 对于蒙面海豹幼仔来说, 这没什么。

If hooded seals drink the fattiest milk, then tammar wallabies prefer their milk loaded with sugar.

如果说冠海豹喝的是脂肪含量最高的牛奶，那么红袋鼠则更喜欢喝加了糖的牛奶。

Of all the seals that live in Arctic, the hooded seal spends the shortest time out on the ice. After just four days, this pup will be weaned and ready to escape to the ocean.

在北极地区的所有海豹当中冠海豹在冰面上停留的时间是最短的。仅仅四天之后小海豹就将断奶，准备撤往海中。
