What is a river otters niche?

River otters occupy a crucial ecological niche as both predators and prey within aquatic ecosystems. They primarily feed on fish, crustaceans, and amphibians, helping to regulate these populations and maintain a balanced food web. Additionally, their activities contribute to the health of waterways by aerating the soil and promoting plant growth along riverbanks. River otters also play a role in nutrient cycling, as their waste products enrich the surrounding environment.
