Dolphinariums is a nightmare for a Dolphin

It does look happy as it runs around the pool, the dolphin with the cute nose. And hula-hop ring over the water jump, it also blithely through. To experience most tourists visiting the dolphinarium.

Reality is just completely different. Dolphins in captivity do not thrive at all. They are trained to make impressive leaps through rewards with treats. Or punishment, if not performing the rehearsed drills.

No space - many diseases
A dolphin is trained to behave unnatural to the audience's sake.

When the show is over, the dolphin is often left to themselves without the opportunity to live out their natural needs. Had it been in the high seas could flood some of the 80 km which is natural for it to travel daily. It can not do so in a pool. Besides the small space, struggling dolphin too often with wounds from sunburn because the water level in the basin is low. It may get eye infections because of chemicals in the water, infections sometimes resulting in blindness.

That dolphins suffer in captivity, several studies show. Autopsy dolphin shows, for example, often obvious signs of ulcers and stress. They typically die of stress-related illnesses or chlorine poisoning. Actual live dolphins in the pool is rarely more than five years. In the wild they live up to 40 years.

The intelligent mammals is simply not being stimulated enough within limited pool areas and are forced to live outside his own species, as it normally is closely linked. It is estimated that about every second dolphin, which is shifted from the sea to dolphinariums die within the first three months in captivity.
