As Jacques Cousteau once said, "There is about as much educational benefit to be gained in studying dolphins in captivity as there would be studying mankind by only observing prisoners held in solitary confinement."
Marine parks have caused the misconception that dolphins and are happy in captivity and are providing an educational service. In reality the majority of marine parks are experienced in entertainment rather than education. Dolphins and other animals are taught to perform unnatural acts such as jumping through hoops and allowing humans to ride them. These acts clearly do not educate people about the dolphins natural life in the wild, nor are they healthy for the dolphins.
Too little consideration has been given to the captive dolphin's quality of life. They live in cement tanks filled with clorine that in no way even begin to resemble their natural habitat. Bizarre and dangerous behavior patterns often occur while dolphins are in captivity. For example, one can only guess why animals equipped with natural echolocation and sonic capabilities have collided with pool walls, resulting in injury and even death.
Dolphins in captivity are short lived as a result of suicide, depression, stress related ilnesses and bacterial infections just to name a few. Wild dolphins can swim up to 100 miles per day but in pools dolphins merely go around in circles. Dolphins spend up to half of their time in the wild hunting live fish, but in captivity they are fead dead fish which results a lack of mental stimulation which causes boredom.
