Why Aren't Great White Sharks in Aquariums? - Thrillist
Jul 11, 2016 - That isn't to say that zoos haven't tried time and time again to house great whites within their aquarium walls
To more successfully hunt fast and agile prey such as sea lions, the great white has adapted to maintain a body temperature warmer than the surrounding water. One of these adaptations is a "" (Latin for "wonderful net"). This close web-like structure of veins and arteries, located along each lateral side of the shark, conserves heat by warming the cooler arterial blood with the venous blood that has been warmed by the working muscles. This keeps certain parts of the body (particularly the stomach) at temperatures up to 14 °C (25 °F) above that of the surrounding water, while the heart and gills remain at sea temperature. When conserving energy the core body temperature can drop to match the surroundings. A great white shark's success in raising its is an example of . Therefore, the great white shark can be considered an because its body temperature is not constant but is internally regulated. Great whites also rely on the fat and oils stored within their livers for long-distance migrations across nutrient-poor areas of the oceans. Studies by Stanford University and the Monterey Bay Aquarium published on 17 July 2013 revealed that In addition to controlling the sharks' buoyancy, the liver of great whites is essential in migration patterns. Sharks that sink faster during drift dives were revealed to use up their internal stores of energy quicker than those which sink in a dive at more leisurely rates.
Aquariums have made dozens of attempts since the 1970s to display a captive great white shark. Most of those attempts ended with dead sharks. By the 2000s, the only group still trying was the Monterey Bay Aquarium, which spent a decade planning its white shark program. In 2004, it acquired a shark that became the first great white to survive in captivity for more than 16 days. In fact, it was on display for more than six months before it was released back into the ocean. The aquarium has since displayed several juvenile Great White Sharks for similar lengths of time, but ultimately ended the expensive program in 2011 due to criticism over injuries the sharks sustained in the tanks, the video explains. It just wasn't working out, especially for the sharks.

Great White Shark Dies After Just Three Days in Aquarium | PETA
That isn’t to say that zoos haven’t tried and to house great whites within their aquarium walls. In fact, every time a great white has been on display, crowds have flocked to see them in .A great white shark which was captured and exhibited in a Japanese aquarium, one of only a few such sharks to ever be displayed in this way, has died just after three days, the facility said Saturday. The shark, about 3.5 metres (11'5'') in length, was trapped in a fisherman's net and taken to an aquarium on the southern Japanese island of Okinawa on Tuesday. It was exhibited in the Sea of Dangerous Sharks section at Okinawa Churaumi Aquarium, but died on Friday, according to the facility. The aquarium, popular for its giant tanks where it exhibits whale sharks, said it is investigating what caused the death of the fish -- of the same species as that featured in Hollywood buster "Jaws". "It is very difficult to keep great white sharks," said Keiichi Sato, an expert in cartilage fish, of the Okinawa Churashima Foundation. Two aquariums in the United States, including Monterey Bay Aquarium in California, have had the species in captive for short periods in the past, he said. "It is rare that the kind of shark is spotted in the coastal waters of Okinawa in the first place, and even if they get caught in a fisherman's net they usually die immediately because they must keep moving at high speed," Sato told AFP. "We have almost no knowledge about the great white's nature, so although it died we would like to share what we learnt from this experience with researchers of the world," he added.
