Happy Fitness Friday, all! While our visitors get good looks at our adult Northern fur seals stretching and speed swimming in the New Balance Foundation Marine Mammal Center, the youngest member of the Aquarium's pinniped family is still getting big and strong behind the scenes. He'll be joining adult swim very soon. Until then, we thought you'd like to see him in action.

Leu is perfecting his porpoising skills in this clip. Notice how his stamina appears to have improved since we put this post!



Keep watching the Trainers Blog for our special new series of posts we're calling What's New with Leu. Just like human babies, this little guy is learning new skills every day and cultivating quite a charming personality. Stay tuned!
