(Thanks to Susan for the tip)
These are sea otters at the Vancouver Aquarium. They like to sleep floating on their backs in the water. And they, well, sort of hold hands while they’re doing it.
Surely, if you’re a couple of otters out on the open sea, you don’t want to drift miles apart while you’re asleep and maybe never be able to find each other again.
And maybe they really like each other!
