GENERAL HISTOLOGY

Detailed explanation-1: -Otters love to rest in groups. Researchers have seen concentrations of over 1, 000 otters floating together. To keep from drifting away from each other, sea otters will wrap themselves up in seaweed, forming something that resembles a raft.

Detailed explanation-2: -Sea otters spend most of their time in the water. They eat, sleep, hunt, mate and give birth in the water. To prevent themselves from floating away in the swirling sea while they sleep, sea otters often entangle themselves in forests of kelp or giant seaweed to provide anchorage.

Detailed explanation-3: -Sea otters spend all of their time in the ocean, including sleeping. Since they must sleep at the surface, they often wrap themselves in giant kelp to keep from floating away. By controlling sea urchin populations, sea otters promote giant kelp growth, as that species is a favorite of sea urchin grazers.

Detailed explanation-4: -They’re also some of the most loveable, due in no small part to the fact that they often hold hands while sleeping so they don’t float away from each other. It’s a gesture that’s not just limited to members of the same family, either. Groups of otters will often link hands while dozing, even if they’re not related.

Detailed explanation-5: -Sea otters sleep at sea, floating on their backs on the surface. They often sleep in strands of kelp which keeps them from drifting.
