Noise pollution has profound effects on marine life behavior. Underwater noise from shipping, sonar, and industrial activities can disrupt communication, navigation, and feeding patterns of marine organisms. Whales, dolphins, and other cetaceans are particularly sensitive, experiencing stress, displacement, and altered migration routes. Fish may exhibit changed schooling behavior or avoid critical habitats. Invertebrates like crustaceans and cephalopods can also be affected. Prolonged exposure may lead to chronic stress, reduced reproductive success, and even physical harm. Mitigating these impacts requires careful regulation.
