Mama sea otter and her fluffy pup

Could it get any cuter than a tiny, ultra-fluffy baby sea otter sitting on its proud mama's belly? Mother sea otters spend an amazing amount of time grooming their pups to keep them warm and dry.

So grooming and keeping up out of the water is important for keeping pups warm enough.
