Great whites are also more injury-prone in captivity as their desire to move can see them ram into the walls of their cages, while the lack of movement can also see them refuse food.īecause of this, keeping great whites captive is now considered inhumane.īut even without these considerations, the price of maintaining a great white enclosure is so high most aquariums wouldn't consider it cost-effective.
