The Sealions are a popular attraction at Colchester zoo, where we visited with the girls this afternoon. In the summer, live shows are put on and large crowds gather poolside to watch these marine animals perform.
But the best of the action happens underwater in my opinion. The sheer effortlessness and grace exhibited by the sealions is quite remarkable. If you have the chance, pop in and see them, either through the underwater tunnel, or from one of the large reinforced windows at the side.
edit: I hope this isn't too dark - it is mid-winter you know!
