Can killer whales see when there are oil spills?

Killer whales, like many marine animals, rely primarily on sound for navigation and hunting, rather than sight. While they can see, their vision is adapted for low-light underwater conditions. Oil spills can significantly impact their environment, affecting prey availability and habitat quality, but killer whales cannot "see" the oil in the way humans might perceive a spill. Instead, they may be affected by the physical and chemical changes in their habitat caused by the spill.
