Aquariums can be really powerful forces for good in the world of conservation.
They, along with animal water parks like SeaWorld, also showcase aquatic animals the viewing public wouldn't normally get to see. Public perception around keeping large animals like orcas in relatively small tanks for entertainment has quickly shifted after the documentary "Blackfish" exposed some of the abuses that take place. However, doesn't it seem strange that if SeaWorld keeps large orcas and many aquariums house many species of shark, that no one has tried to put a Great White on display?
Actually, they have, but each shark has died shortly thereafter. Why does this happen? IFL Science has the answers.
The first time a Great White was ever put on display was in the 1950s at a place called Marineland. It died within a day. SeaWorld also attempted it a few times in the 70s, 80s, and 90s, but each time the shark died or had to be released.
