CNN: What are the benefits to keeping orcas in captivity?
SeaWorld: The primary benefits are identical for any species in any accredited zoological institution: education and science. At SeaWorld more than 11 million people each year (hundreds of millions since our first park opened its gates in 1964) have experienced killer whales in a way that is personal, enriching and inspirational. Learn more here. It is our hope that every person who has visited SeaWorld leaves with a greater understanding of and appreciation for all the animals we display, including killer whales. I have attached two documents that outline some of our peer-reviewed contributions to the scientific understanding of killer whales. Note that this is just killer whales. We have similar bibliographies for many of the species living at SeaWorld.
It occurs to me that the main reason we know that they are social and emotional is because they have been so Zoologically studied.
