Instances have been observed where orcas appear to offer dead prey to humans.

Jared Tower, from the marine research organization Bay Cetology, was filming orca pods (Orcinus orca) as they feasted on seabirds in Alert Bay, Canada, when he witnessed a fascinating incident. Two whales, named Akela and Quiver, approached a camera tower with birds held tightly in their mouths. Akela, the younger female, dropped a dead bird in front of the tower and lingered nearby, seemingly curious about the human presence. Quiver followed suit, dropping his bird and waiting as well.

In an unexpected turn, both whales reclaimed their prey and swam back to the tower. “I remember thinking, did that really just happen?” Towers recalls. This wasn’t the first instance of such behavior; similar actions were noted in 2015 and 2018, when a young female orca presented a researcher with a Harbor Seal pup, showcasing a killer whale’s desire to share its catch with humans.

Through interviews, Tower uncovered another 32 similar cases between 2004 and 2024. One notable account involved a young male orca from New Zealand, known as Funky Monkey, who repeatedly approached researchers while carrying a long-tailed stingray. In total, 18 different prey species were identified in these instances, including gray whales, seals, jellyfish, birds, otters, rays, turtles, and others.

This behavior has been previously recorded within orca pods. “They exist in a deeply interconnected social structure and share their prey amongst one another,” noted Towers.

However, it appears this behavior extends beyond their own kind. “They engage in actions that not only benefit themselves but also foster goodwill towards another species,” explains Lori Marino from New York University, who was not affiliated with this research.

Tower suggests that such actions indicate the potential for general altruism, or kindness, among killer whales. They demonstrate curiosity and the boldness to engage with other species, he asserts.

This propensity for generalized altruism makes sense in a social structure where collaboration is key for survival. Moreover, killer whales are among the few marine predators capable of overwhelming their prey at times. “They can opt to leave it behind, play with it, or use it as a means to explore inter-species relationships,” Towers explained.

For many killer whales, adaptability as generalist predators sparks curiosity and exploratory behaviors. “Exploration is a means to alleviate uncertainty,” Towers said. “They are actively learning about us by probing the waters.”

Tower also posits that this behavior signifies that orcas possess a theory of mind, a trait observed in certain birds, apes, and other marine creatures like dolphins.
