Scientists have captured rare footage of killer whales and Pacific white-sided dolphins hunting together near the coast of British Columbia, Canada
The findings, published in the journal Nature Scientific Reports, is the first recorded evidence of the two species working together, according to researchers.
They studied the whales using drones and camera tags to understand feeding behaviour.
“Not only were the killer whales orienting [themselves] towards the dolphins at the surface, but when the dolphins started to dive, our tagged killer whales would start to dive,” lead researcher Dr Sarah Fortune from Dalhousie University in Canada said.
