Watch Rare Video of Orcas Teaming Up With Dolphins to Hunt Giant Salmon

Nature can be brutal. But animals also help each other, sometimes in ways unimaginable to the human observers. For instance, take the case of killer whales and dolphins, two top marine predators. According to new research, these mammals appear to have forged a special relationship—which scientists caught on camera for the first time.

In a Scientific Reports study published on December 11, researchers describe how killer whales, or orcas, collaborate with Pacific white-sided dolphins to track and feast on salmon off the coasts of British Columbia, Canada. The partnership was far more sophisticated than the two species sharing a meal, the paper reported, as the tag team capitalized on the other’s natural strengths.

For example, orcas used dolphin echolocation cues to locate large salmo
