The female orca was found far from her normal hunting ground with six whole sea otters in its stomach and one lodged between its oral cavity and the esophagus.
Scientists in Russia discovered seven perfectly intact sea otters in the belly of a beached orca, according to a new study. The doomed killer whale was found far from its normal hunting grounds, raising the question of what it was doing there.
Instead, they hunt seals, sea lions, dolphins and even other whales. And whatever prey species they hunt,"they normally don't swallow prey whole — they usually tear it apart and eat only the best parts," Filatova said. Gulping down whole sea otters was likely challenging for the doomed orca, as adult sea otters can reach up to 5 feet long. The researchers think the orca may have taken this extraordinary step because it was starving.
This is the first time any member of this orca population has ever been found in the Western Pacific, leading the study authors to hypothesize that the orca learned this hunting strategy elsewhere. Feeding strategies are usually passed on from mothers to calves, the study authors noted.
