A new study published in the journal Nature Communications has revealed that predation by killer whales is much more widespread than previously thought. By using radio tags to track the movement of killer whales, researchers were able to monitor and record their predation activities in the waters off the coast of British Columbia, Canada. They found that killer whales targeted a wide range of prey species and that their predation behavior was much more diverse than originally believed. The findings suggest that killer whales should be given more conservation attention, as their predation could have a significant impact on the health of the marine ecosystem.
