Which sea creatures are known to hold hands while sleeping?

• Sea otters:Sea otters are known to hold hands while sleeping so they don't drift apart. Sea otters sleep in "rafts" — a group of floating otters all joined together. Not all species of otters hold hands; this is a characteristic unique only to sea otters. These furry creatures, the largest member of the weasel family, are even known to wrap sea plants around themselves to secure the bond and prevent families from becoming separated. Because newborns struggle to grasp their parents' hands, the mother will turn her body into a crib for her baby by floating on her back and letting her baby sleep on her chest.
