Drones and suction cup-attached cameras suggest killer cooperation between orcas and Pacific white-sided dolphins.
Instead of competing for food in the waters off Vancouver Island, Canadian scientists say the animals may be engaging in cooperative foraging.
The footage finds the orcas following the dolphins down deep.
The orcas get quieter, perhaps eavesdropping on the dolphins' echolocation.
Zeroing in on the prize, Chinook salmon.
Too big for the dolphins to swallow whole.
The orcas bring it to the surface, break it apart, and the dolphins get the scraps.
The researchers say more study is needed to look at ecological implications.
It's published in the journal Scientific Reports.
