many of the enrichment routines are actually based around behaviours that are needed to better care for the animals. for instance, training a command to swim to a platform and breach up and present their underside? this lets veterinarian more easily perform examinations. training a jump to a particular side of a pool and staying there can let the maintenance crews work on filters after hours. modern enrichment routines have many purposes beyond entertainment, and if they can also draw paying crowds and donors, so be it for the better. a marine mammal specialist at your local aquarium can probably talk your ear off on the topic if you were to go ask about the "tricks".
