Why Sea Otters Hold Hands
1
Sea otters sometimes hold hands while they sleep. There's a practical reason.
2
They sleep floating on the water, and currents could easily pull them apart.
3
So they link paws, or wrap themselves in kelp, to stay anchored.
4
They don't have blubber like seals. Instead they have the densest fur of any animal, up to about a million hairs per square inch.
5
Many even keep a favorite rock in a pouch of skin under their arm, for cracking open shellfish.
6
A tool, a blanket of seaweed, and someone to hold onto. Not a bad way to sleep.
