– Great whites prefer open waters, where they can swim very long distances. When confined in a tank, they can continuously run and bump into the glass, causing damage to their noses and sides, which can ultimately kill them.
– It’s horribly hard to take care of them. They’re actually really picky when it comes to food, and because of their size, they have to eat a lot. There have also been times where great whites in captivity would eat their tank mates.
– They refuse to be fed by humans. Great white sharks are natural hunters, and they need the thrill of hunting to survive, they will not survive by eating already dead fish. Because of this, the sharks refuse to eat until they are released back in to the ocean or starve to death.
– Many people believe that sharks become depressed and even die in captivity due to aquariums using the incorrect water solutions, without enough saline.
– They become depressed in captivity, another reason why they bump in to the class and refuse to eat. In a depressed state, great whites tend to become more aggressive.
TL;DR: Great white sharks can not and will not be confined in captivity because they can only survive in their natural habitat.
