After seeing the Killer Whales in the open ocean, I started researching how endangered they really are.
Astoundingly, I came across thousands of sites and groups protesting against marine mammals and small cetaceans(dolphins etc) in captivity, and knew there'd be reasoning behind it. I carried on researching and watched clips of captive mammal shows and saw "The Cove"(if you haven't seen it, do). They all clarified the idea that marine entertainment parks are extremely cruel and falsely advertise that they're interested in the wellbeing of their animals. Realistically they just want your money for another porsche.
I also recently found out that Iceland is taking away it's law against whaling, which is a bad decision and will definitely not have a positive effect on the quickly dropping numbers of mammals in the ocean. 
"Free Willy" is another awesome movie telling it straight!
After scanning around finding interesting information on this topic, i came across a few articles and photos of wounded show dolphins.
A common one is the fin of the Killer Whale starting to droop, this is caused by the change in environment and the lack of pool depth in captivity.

But, a more extreme injury I came across were rashes and huge chunks of skin missing from the chin of many dolphins.

50 percent of marine mammals born in captivity will die in the first four months of their life.

I apologise for the dark and sad tone of this post, but I believe everyone should know about the creepy minds of those corporate men who own ocean entertainment parks to become snobby billionaires and don't care in the slightest about the animals bringing in their money. It's gross.
