Southern Resident orca hunting behavior studied for clues to survival

Scientists have learned a lot about how Southern Resident Orcas catch fish at the surface during the day, but what happens at night or deep down in Puget Sound has remained a mystery.

"We wanted to know how they catch fish underwater. They go on these deep dives to find salmon that are 100 to 600 feet underwater," explained Jennifer Tennessen, a NOAA Researcher, WWU Research Associate, and contractor with Lynker.
