FRESHWATER MUSSELS
DESCRIPTION
Freshwater mussels are bivalve mollusks that live in freshwater environments such as rivers, lakes, and ponds. They play a crucial role in aquatic ecosystems by filtering water and providing habitat for other species.
FUN FACTS
- Freshwater mussels can filter up to 50 gallons of water per day | Some species can live for over 100 years | They have a unique reproductive strategy involving fish hosts for their larvae
