Killer whales are some of the oceans’ top predators, but even they can be exposed to environmental pollution. In the largest study to date on North Atlantic killer whales, researchers in ACS’ Environmental Science & Technology report the levels of pollutants in 162 individuals’ blubber.
Monika Wieland Shields, Director of the Orca Behavior Institute, has observed orcas in the Salish Sea, a marginal sea of the Pacific Ocean located in the Canadian province of British Columbia and the U.S. state of Washington, since 2000.
Killer whales (also known as orcas) are intelligent predators. While it’s known that killer whales in the Pacific Northwest exploit widely different food types, even within the same region, we know much less about the feeding habits of those found throughout the North Atlantic.
