What are the adaptations of European otters?

European otters have several adaptations that enhance their survival in aquatic environments. Their streamlined bodies and webbed feet enable efficient swimming and diving. The thick fur provides insulation against cold water, while a layer of fat helps in buoyancy. Additionally, their keen sense of smell and acute hearing assist them in hunting prey, primarily fish and crustaceans, in various habitats including rivers, lakes, and coastal areas.
