Why Humpback Whales Protect Other Animals From Killer Whales

“Two humpback whales were already on the scene as the killer whales, or orcas, attacked the grays. But after the calf had been killed, around 14 more humpbacks arrived-seemingly to prevent the orcas from eating the calf.”

Biological Altruism

“In evolutionary biology, an organism is said to behave altruistically when its behaviour benefits other organisms, at a cost to itself.
