Yes the shedd keeps pacific white-sided dolphins. This species of dolphin adapts well to captivity, however I don't agree with keeping them at all. I think in the other thread, those, including myself, who used the Shedd as an example of an outstanding aquarium, were thinking in terms of location and appearance of the facilities and not the particular exhibits. That said I believe the shedd does have a very good research and educational mandate. There are about 50 pacific white-sided dolphins in captivity in the world, an estimated 50,000-90,000 were killed for food and as by-catch in the past 20 years. I guess the shedd hopes their exhibit will help preserve them through education and endearing them to the crowds. Apparently they had a baby dolphin die this summer.
