Freshwater species are organisms that live in rivers, lakes, ponds, and streams. These species include a variety of plants, fish, amphibians, and invertebrates that thrive in non-saline water. Common examples of freshwater fish are trout, bass, and catfish, while amphibians like frogs and salamanders also inhabit these ecosystems. Freshwater ecosystems are vital for biodiversity and provide essential services, such as water filtration and habitat for wildlife. They support food chains and are crucial for the survival of many species. Conservation efforts are important to protect these habitats from pollution and climate change impacts.
