How do river otters survive in the winter?

A double layer of fur—dense underfur for warmth plus a waterproof outer layer—and a second, clear eyelid allow otters to see and swim gracefully in even the iciest of waters. If there are air pockets under the ice, otters can stay underwater for long periods of time without having to surface.
