Keeping any large marine predator in captivity is a challenge. While it has been done with both mammals and some sharks, it has never been successful with Great White Sharks. The longest a Great White Shark has survived in captivity is something like 4 – 5 weeks, if I am not mistaken.
I have heard this can be because they are used to swimming such great distances in the wild. However, both Killer Whales and Dolphins also swim great distances per day in the wild and are known to survive (sometimes even breed) in captivity.
So why is it that Great White Sharks are so hard to keep in captivity?
I am aware that most large predators kept in captivity live less long than in the wild, with some the exceptions (crocs just chill). It just seems extreme to me that Great White Sharks die within such a short period of time.
