SeaWorld said that Tilikum’s age at his death was “near the high end of the average life expectancy for male killer whales”. The oldest killer whale known died this week and was thought to be around 105.

Blackfish showed the treatment of Tilikum and other orcas at SeaWorld. It showed how the company took the animals and forced them to perform in shows, and how that treatment had apparently led to the whales’ strange and violent behaviour.
