Some animals are probably just not meant to be in captivity. Last Tuesday, a great white shark (Carcharodon carcharias) was accidentally caught in a net in Japan. The 11.5-foot male shark was taken to the Okinawa Churaumi Aquarium, where it refused to eat ever since.
The great white lived three days at the aquarium. IFL Science notes reasons why such an animal does not do well in captivity: “First of all, their natural temperament is to cruise the open ocean for hundreds of kilometers at a time, requiring a sizeable tank that most aquariums are not equipped for. If denied this, they can become depressed and even more aggressive. They also need to continually swim in order to have a constant, fresh water flow over their gills… [it is suggested that] the extremely harsh and artificial environment of a glass tank could overwhelm or confuse these sharks’ incredibly sharp electrosensitivity.”
IFL Science reports that the shark’s death will be investigated.
