Sea otters hold hands while they are asleep. A pair of these animals roll over onto their backs and floats in the water while sleeping.
They usually choose a place near the shoreline where the water is calm. But, after heavy rain, a river can start to move fast. Even if it hasn’t rained in a while, a river is still flowing at a constant rate of speed.
This puts a pair of sleeping otters at risk of being carried downstream! So, these animals hold hands to stay together if the current happens to take them away from their nest. Sea otters holding hands are also concerned about losing family members while sleeping.
When it comes to seeking a partner, male otters are fiercely competitive. These critters also clasp hands to avoid losing their significant otter to another male.
