In areas where the water temperature drops below 12 degrees Celsius (54 degrees Fahrenheit), orcas may not be able to find enough food to survive. They use these senses to help them find prey and avoid predators. In the Pacific Northwest, where both types of orcas live, declining water clarity has been linked to a decrease in salmon populations. If the water is too murky, they cant see whats around them and may miss an opportunity to eat. In addition, as top predators, orcas are also at risk from the accumulation of toxins in their food chain. Orcas are found in all oceans, from the cold waters of the Arctic to warm tropical seas.They eat a wide variety of prey including fish, squid, birds and marine mammals such as seals and dolphins. Some biotic factors are fish, algae and krill. Additionally, noise pollution from boats and other sources can disrupt orcas echolocation abilities, making it difficult for them to find food and communicate with each other. However, it seems likely that they at least prefer clear waters, as this would allow them to better see both their prey and any potential threats.In areas with murky or dark waters, orcas may have a harder time finding food and avoiding danger. NOAA Fisheries scientists collaborated with our partners to develop an automated process to translate these data into, Water Clarity Reflects And Influences Ecosystem Structure And Change.
