Anyone who has seen the tragic documentary Black Fish will know the horrifying story of Tilikum, a killer whale kept in captivity who then started to turn on her trainers and a quick cover up ensued with SeaWorld desperate to minimize the damage their brand had suffered. Jumping out of the water and grabbing Dawn Brancheau by the ponytail in February of 2010, the whale dragged her underwater and would not let her go. Shockingly, the attack took place in front of a crowd of spectators as they awaited a demonstration between Brancheau and the killer whale. Tilikum was involved in the death of two other trainers also, the photo shows Tilikum dragging another trainer repeatedly down by their ankle but they managed to escape.
