During a period of social activity among several family groups of killer whales, a young sea lion is curious and swims with the whales. The head of the sea lion is out of the water on the right side of the whale's fin. Normally sea lions are prey of the whales, but the killer whales were not interested in feeding and instead were very playful and the sea lion may have sensed that and joined in.
