Freshwater pearl mussel

Freshwater Pearl Mussel

The freshwater pearl mussel is a very special type of river creature. It lives in clean, fast rivers and streams. These mussels are not fish, but they are called "mussels" because they have two shells that close together to protect them. They are found in many cool places like Canada, New England, and parts of Europe.

People once looked for shiny pearls inside these mussels. The inside of their shells has a pretty, shiny layer. Some of these mussels can live for more than 100 years! That makes them one of the oldest animals that live in freshwater.

Freshwater pearl mussels need special homes to survive. They like clean gravel and sand at the bottom of rivers. They also need certain fish, like Atlantic salmon and sea trout, to help them when they are very tiny. These tiny mussels attach to the fish and grow until they can live on their own.

Because these mussels are rare now, people work hard to protect them. They help by cleaning rivers and making safe places for the mussels to live. This way, future generations can enjoy these amazing river creatures.
