Orcas, also known as killer whales, have a surprising reputation for sharing their food with humans. A recent study analyzed 34 instances of prey-sharing by orcas over a span of two decades, shedding light on the altruistic behaviors of these fascinating marine mammals.
Belonging to the dolphin family, orcas are highly intelligent and social creatures found in all oceans. They exhibit complex behaviors, communicate through unique calls, and live in matrilineal societies where older females play a crucial role in shaping the behavior of younger members. Orcas are known for their rich culture, including wearing salmon hats and using kelp-based tools for grooming.
The study revealed that orcas engage in prosocial activities such as sharing food with other cetaceans and even humans. Lead author Jared Towers, an ecologist at Bay Cetology in Canada, noted that this behavior may be a way for orcas to build relationships with other species, including humans.
The research spanned two decades and documented numerous instances of orcas sharing prey with humans. These interactions were initiated by the whales themselves and not as a result of humans approaching them. The orcas approached people on boats, in the water, and on shore, showcasing their willingness to share food across different contexts.
In most cases, the orcas intentionally released the food in front of humans, sometimes playing with the food items before offering them. Despite their efforts, humans often ignored the offerings, leading the orcas to make additional attempts to share. The study highlighted the rarity of such interspecies food-sharing behaviors in the wild.
The researchers suggested that orcas may be motivated to share food with humans as a way to explore, play, and establish relationships with a different species. Their advanced cognitive abilities and social nature may drive them to forge connections with other beings, including humans.
Overall, the study underscored the evolutionary and intellectual convergence between humans and orcas, both of which exhibit high levels of encephalization. These food-sharing interactions serve as a unique example of prosocial behavior in non-human animals and highlight the complex social dynamics of orca communities.
Published in the Journal of Comparative Psychology, this research sheds new light on the remarkable behaviors of orcas and their capacity for building relationships across species boundaries. As human and orca activities continue to overlap, these interactions may become more common, offering valuable insights into the social complexity of these fascinating marine mammals.
