Jared Towers, executive director of Bay Cetology, a research nonprofit based in Alert Bay, British Columbia, was on a boat in waters at the northeastern end of Vancouver Island, British Columbia, when a transient orca offered a freshly-killed harbor seal pup. “I did not have my phone out when T046C2 came over and dropped the seal,” Towers wrote in an email, “But I had time to get it when she left it there sinking before circling around to pick it up again.” He took a photo, showing the orca’s still-open, toothy mouth after just releasing the seal.
Towers says this demonstrates that killer whales are capable of generalised altruism, or kindness. It also shows that orcas can recognise sentience in others and are curious and bold enough to experiment across species, he says.

This generalised altruism makes sense in social societies where members benefit from cooperation. Killer whales are also some of the few marine predators that occasionally find themselves with excess prey. Sometimes, a pod will kill a larger whale than they can finish, for example. “You can just leave it, you can play with it or you can use it to explore relationships in your environment,” says Towers.

In each of the instances recorded over two decades, orcas approached a person within a length of the orca's body, and dropped freshly hunted prey in front of the human.
