Those changes propagate through the food web to affect productivity of higher trophic levels like fish. Water pollution affects killer whales in a variety of ways. Vision is critical to the success of predators who hunt by sight, and the survival of prey that depend on vision to evade predators. Although Orcinus orca seems to prefer colder waters, they have also been observed in tropical waters. It also reduces the ability of orcas and other predators to smell their prey which could impact their ability to find food and survive in the wild. This behavior is not considered stranding. This causes a number of problems for marine life, including making it harder for animals to extract oxygen from the water.There is already evidence that ocean acidification is affecting orcas in a number of ways. Variation in water clarity over the northern shelf is notable because primary production here typically continues throughout the summer by virtue of high surface clarity. This increased acidity makes it harder for marine organisms to build shells or skeletons from calcium carbonate which can lead to deformities or even death. Implications for Bering Sea Fish and Fisheries Management, Water clarity affects visibility and therefore catchability.
