Northern resident killer whales appear to use dolphins as ‘scouts’, in a surprising cooperative hunting strategy
Orcas and dolphins have been spotted for the first time working as a team to hunt salmon off the coast of British Columbia, according to a new study which suggests a cooperative relationship between the two predators.
The research, published on Thursday in the journal Scientific Reports, shows interactions between northern resident orcas (also known as killer whales) and Pacific white-sided dolphins are not just chance encounters while foraging.
