A record number of orcas have died this year after snacking on fish hauled up by commercial trawlers in Alaska but then getting entangled in fishing gear, according to the National Oceanic and Atmospheric Administration .
Orcas are highly intelligent and innovative marine mammals that can imitate and learn from each other through a process called social learning. Orcas are known to exploit human fisheries, which provide them with all-you-can-eat buffets worldwide, according to a 2022 NOAA Fisheries report. Longline fisheries, which dangle lines of baited hooks to catch various fish species, are particularly attractive, as orcas can easily pluck food off the hooks.
For the other nine orcas,"NOAA Fisheries is analyzing collected data to determine the cause of injury or death and determine which stocks these whales belong to through a review of genetic information," the statement said.
