Whales and dolphins are very intelligent mammels. They don't belong in a large swimming pool, preforming tricks for thousands of people and making tons of money for Sea World. Does anyone remember Keiko from "Free Willy" fame? The Oregon Coast Aquarium built a special tank for him and rescued him from a filthy dump in Mexico. They rehabilitated him and let him go in the wild near Iceland where he was captured when he was very young. I saw him in Oregon and he was magnificant. His skin conditions cleared up and he learned to hunt for live fish instead of having dead fish thrown at him. He has since died but at least he died in the ocean where he belonged. By the way, did you know that even though they are called killer whales they are really the largest member of the dolphin family?
