freshwater invertebrates

Freshwater invertebrates are small, spineless animals that live in rivers, lakes, and ponds. They include a variety of species such as insects (like dragonflies), mollusks (like snails), crustaceans (like crayfish), and worms. These organisms play essential roles in the freshwater ecosystem, such as breaking down organic material, serving as food for fish and birds, and helping to filter water. Their presence and health can indicate the overall quality of the water environment, making them important for biodiversity and ecological studies.
