To celebrate Mother's Day, we're in California's Monterey Bay, where a sea otter mom gives her 3-day-old pup a place to snuggle and gives us an amazingly cute picture to boot. These incredibly photogenic animal moms shower their kids with attention, cradling them and grooming them for hours. But all that love is more than a gesture of affection, as newborn sea otter pups can't swim. A pup is totally dependent for about six months, so mom will carry it around on her stomach like you see here. When the little one does venture into the water on its own, mom will rub the pup to fluff its coat, which causes the fur to retain air bubbles, insulating it from chilly water and causing the youngster to float like a cork.
