Yes, it's true, sea otters hold hands
This photo of sea otters has made its way around the internet multiple times, and usually with the caption that sea otters hold hands to keep from floating away from each other. Yes, it's true — often a mother and pup will hold on to each other while sleeping to keep from drifting away from one another. But that isn't the only strategy sea otters have. They also utilize kelp! Sea otters wrap themselves in long strands of kelp which grow from the sea floor all the way up to the surface of the water. They use the kelp as an anchor so they can sleep without worry of floating out to open ocean. This adorable photo shows mama and baby using both strategies!
