“…building a tank the size of Rhode Island would not be big enough for a six-ton ​​male killer whale like Tilikum, an animal capable of swimming 100 miles a day,” says one anonymous whale expert. Whales have been in captivity since 1861, when PT Barnum exhibited the first live whale captured in Canada. However, Barnum did not know how to care for the mammal and it died after only a week in captivity. (Animal Legal and Historical Center, 2014) Being close to killer whales could give us clues about how they interact with each other, including their physical behavior, their dialect, and how their groups work together as family unit. However, we find that whales that belong in the wild suffer in captivity. Killer whales have never harmed a human being in the wild. In captivity, there have been numerous incidents where killer whales have injured or even killed their handlers. What would make them do this in captivity, but not in the wild? They are known to resort to aggression towards themselves and each other, in what scientists consider stress-induced behavior. (Animal Legal and Historical Center, 2014) The evidence against keeping these wild animals in captivity is growing and we must re-evaluate the value of capturing and keeping killer whales for education, enjoyment and entertainment. profit. Captivity is a term that covers a range of definitions. The least restrictive would be an enclosed space that attempts to meet the physical, social, physical and medical needs of these animals. The most restrictive provide limited space for movement and social interaction and do not provide necessary regular medical care. When we talk about killer whale dialect, we're talking about... middle of paper ... the mistakes we've made and we're doing our best to fix what's wrong now. Works Cited • “Navigation”.
