This photo was taken two years ago during a visit to Sea World, Orlando. The sea lion pictured here must have been an old animal that used to perform, as when my wife and I waved to it as a joke, it waved back. Indeed, the best part of the day was throwing of few sardines to the seals and sea lions in the enclosure, although I was deeply saddened by the way most of the marine mammals in the park were kept.
