Bliss is a seaweed wrap and a group nap.

Except for some that stake out breeding territories and live alone, male sea otters tend to rest and sleep in rafts. Rafts range from two to 60 or 100 animals. Females and their pups also gather in rafts. Although researchers have recorded otter sounds such as sneezes, distress calls, and pups calling for mothers, they don't know much about sea-otter sounds.

Before napping, otters may wrap kelp or other seaweed around their bodies to anchor themselves. They float on their backs and keep their flippers and paws out of the water to reduce heat loss.
