Drone footage reveals orcas hunting unexpected prey off Chile for first time - Orcas are intelligent apex predators with an impressively varied diet and unique behaviours

The Humboldt Current’s orcas have yet to be assigned to an ecotype, and their hunting behavior provides clues about where the mysterious population might belong, researchers say.

On multiple occasions, scientists and citizen scientists observed the sleek and efficient predators feasting on dusky dolphins ( Lagenorhynchus obscurus ).
