First, Hotter and Otter
It’s hard to stay warm under water. Anybody who has ever said ”I’m… not… cold!” with blue and shaking lips after an hour splashing in the lake on the year’s hottest day knows this.
Mammals that spend their time in the sea have developed thick layers of fat. This blubber serves to insulate against heat loss.
The sea otter has no blubber. The marine weasel relies on an insulating layer of air instead, trapped close to their skin in one of the thickest furs of any animal. This lets them lie back and sleep in a bed of water, of course.
Now, want to look under the fur and fat of an email?
