Photo by @brianskerry | An orca is about to eat a herring in the waters of the Norwegian Arctic. Orca migrate into fjords in this region during late fall and winter to feed on herring that often overwinter here. In late November the polar night occurs, with weeks if darkness on end. Successful feeding by the orca involves complex communication and echolocation; such specialized feeding strategies are examples of culture found among whale and dolphin families. #orca #norway #whaleculture #smartanimals
