Blackfish is amazing. Watch it on Netflix, there is another documentary on Killer Whales that comes up on the “recommended because you watched Blackfish” que that is great too because it shows the wild killer whales in their habitat, how they will adapt and learn to kill different creatures like sea lions, stingrays, great white sharks,dolphins and larger whales. That and it brought up the fact that killer whales are not actually whales, but rather a larger type of dolphin. It’s strange to watch the two documentaries back to back because Blackfish highlights humanity’s acts of cruelty against killer whales and the second shows a pack of killer whales meticulously fight a young humpback whale away from it’s exhausted mother only to eat the creature’s lower jaw. There is a very strange dichotomy in which the killer whale is normally friendly around people in the wild, yet savage to most other sea creatures it could prey upon. The land equivalent would be like going out into the African wilderness to see a pack of gigantic lions slaughter an elephant, only to have them come up to you to be petted like a dog.
