Eli5: Why are orcas, lions or tigers abled to be trained as performance animals at aquariums and zoos but others like a cheetah or shark are not?

You could probably train a cheetah if you really wanted to.

Animals with zero social behavior like a shark are very difficult to train because there’s no social instinct to build upon.  They’re not good parents or good friends, everything is food or foe.

Lions and Orcas are highly social animals and the trainer becomes part of their social group to work with them.  Tigers are less social, and harder to work with.
