One research team has observed killer whales trying to share their prey with humans, while another spots the giant mammals using ‘massage brushes’.
Already considered one of the most intelligent species on the planet and nicknamed ‘humans of the sea’ by some, scientists believe they now have evidence of a concerted effort by the ocean giants to establish a relationship with people.
Newspaper reports have compared the act of orcas trying to share their kills with humans as akin to pet cats leaving prey as a gift to their owners. This is the first time such behaviour has been seen in the wild.
First published in the Journal of Comparative Psychology, the study conducted by Canadian, New Zealand and Mexican scientists documents 34 interactions between people and killer whales wherein food was offered. Notably, these occurred in multiple regions, including California, Norway and Patagonia.
‘Orcas often share food with each other. It’s a prosocial activity and a way that they build relationships with each other,’ study lead author Jared Towers said. ‘That they also share with humans may show their interest in relating to us as well.’
Meanwhile, a separate study has captured footage of killer whales fashioning ‘body brushes’ off the coast of Washington DC. Appearing to use these like massage tools, which they use on each other. This would be the first time marine mammals have been found modifying an object to create a specific tool, which may aid in the process of moulting dead skin.
