Occurred on December 21, 2015 / Monterey Bay Aquarium, California, USA
Info from Licensor: "After hearing that a wild female sea otter had given birth to a baby on the morning of December 20th, we made our way to the aquarium to see if she was still in the protected tide pool area. When we arrived, we were greeted with the sight of mother sea otter grooming, swimming, and resting with her pup. I took a few videos and many photographs of mom and her newborn pup."
