Captive orcas, or killer whales, are large predatory marine mammals that were first captured live and displayed in exhibitions in the 1960s, and soon became popular attractions at public aquariums and aquatic theme parks due to their intelligence, trainability, striking appearance, playfulness in captivity and sheer size. However, the captive environment usually bears little resemblance to their wild habitat, and the social groups that the killer whales are put into are foreign to those found in the wild. The practice of keeping killer whales in captivity is controversial.
