Joyful sea otter floating on its back in turquoise water

A close-up, hyper-realistic photograph of a wild sea otter floating on its back in sunlit, turquoise ocean water. The otter is completely overwhelmed with joy, its eyes are tightly closed, and its little paws are pressed against its cheeks, giggling uncontrollably. Bubbles and water droplets are splashing around it. The background is soft-focus kelp and sparkling sunlight. National Geographic style photography, highly detailed, expressive, vibrant colors, natural daylight.
