Even the harbor seals get in on the activities on Fitness Friday. Reggae here is stretching his flippers with a toy. It looks like he's doing a workout with a medicine ball. Or is he playing tetherball with himself? Ah, you decide, just take a look.
Harbor seals may not gallop about their exhibit like the sea lions and fur seals. With shorter flippers, they get around in a much different way. (Compare the two modes of locomotion on land in this post. They even swim in different ways!)
But that doesn't mean the harbor seals aren't active. See how they can dance in the water, do crunches while on land and spring out of the water for a harbor seal high-five!
