Otter and toddler laugh and frolic

(CBS) - When it comes to physical strength, wild animals probably have toddlers beat. But when it comes to raw energy? That is a much closer race. Speaking of races, here's a toddler and an otter running back and forth in an aquarium. They look pretty evenly matched. But which side of the glass is having more fun? Hit play and decide for yourself.

Sea World, San Diego is the scene of this adorable foot race. Otters are naturally playful animals. And we all know there's nothing more playful than an active toddler. It's a little surprising we don't see this sort of thing more often.
