Animal captivity is the capturing and holding of an animal. Animals have been held captive for entertainment purposes and domestication. As of 2016, 63 whales and dolphins who are held captive have significantly less space than they would have in the wild. Marine mammals in captivity have demonstrated behavioral changes in response to the death or separation of a pod mate or family member.
Dolphins Captive dolphins are six times more likely to die than those in the wild because of the stress and poor treatment that they endure, living on average 40 years less in captivity than they would in the wild. The stress of captivity prevents dolphin reproduction, with rare exceptions. Dolphins in their natural habitat spend approximately 80% of their time deep underwater and swim about 40 miles per day. Dolphins in captivity spend about 80% of their time above water and swim just a few miles per day.
Orcas for more than 50 years. In the wild, orcas swim about 100 miles per day and only spend approximately 10% of their lives at the surface of the ocean. In captivity, orcas cannot swim to their necessary depth, causing sunburn and blisters. The extended exposure to open air can cause the dorsal fin to collapse. The orcas often die from pregnancy, disease and stress. The orca brain is among the largest and most complex of all marine mammals. Orcas appear to understand that they are in captivity under human care, and they depend on their pod mates and family for survival; it is rare for them to survive on their own. An orca named Loita at the
Miami Seaquarium, captured at four years old and in captivity for almost 50 years, was set to be released but died in the summer of 2023 before she could be freed.
Prevention of captivity The
U.S. Congress passed the
Animal Welfare Act of 1966 to protect animals who are under human care. The
Marine Mammal Protection Act, signed into law in 1972 by President
Richard Nixon, prohibits the capture of marine mammals. ==See also==
