Have you seen the documentary Blackfish by Gabriela Cowperthwaite? It is an alarming look at the distress endured by killer whales held in captivity. I learned that killer whales (also known as orcas) are incredibly social mammals, living in family units with mothers protecting and caring for their young their entire lifetime. I was intrigued to learn that orcas have heightened emotional capabilities that surpass even humans, and they are believed to be able to communicate with their own form of language.
In the wild, these are truly majestic creatures. In captivity at amusement parks such as SeaWorld, these are desperate and sad creatures. This is an emotional and worthwhile film to watch.
