Freshwater Mussels

The image shown is a representative illustration and does not depict every individual animal in this category.

Total number of species approx.: 1000

Freshwater mussels are among the most important yet overlooked animals in rivers, lakes, and streams. Living partially buried in sediment, they filter vast amounts of water each day, removing algae, bacteria, and organic particles. Some species can live for decades, making them long-term stabilizers of freshwater habitats.

Their life cycle is closely linked to fish, as mussel larvae temporarily attach to fish gills or fins to disperse upstream. By clarifying water and recycling nutrients, freshwater mussels support aquatic plants, insects, and fish communities. Their presence is a strong indicator of clean, well-functioning freshwater ecosystems, though many species are now threatened by pollution and habitat loss.

From the entrance you dive parallel to the shore towards the east in the 3m range. Later the bottom starts to slope slightly. The most interesting area here is the 15m area, because here you can find many trees, bizarre branches and prosperity garbage, like bicycles.
