Chameleon Mussel

Lampsilis fasciola, commonly known as the Wavy-Rayed Lampmussel, is a species of freshwater mussel native to North America. These bivalves are typically found in medium to large rivers with stable substrates, where they filter feed on organic particles. *L. fasciola* plays a vital role in maintaining water quality and ecosystem health by filtering and cleaning the water. They have an elongated, slightly curved shell with distinctive wavy ridges on the posterior end, giving them their unique appearance. Unfortunately, like many freshwater mussels, Lampsilis fasciola faces threats from habitat destruction, pollution, and invasive species, making conservation efforts crucial.

It earned the nickname "Chameleon Mussel" due to its remarkable ability to change its shell color and pattern. This species can alter its appearance to match the substrate it inhabits, allowing it to blend in with its surroundings and evade predators. By mimicking the colors and patterns of the riverbed, the chameleon mussel enhances its chances of survival. This unique adaptive strategy showcases the remarkable evolutionary adaptations of Lampsilis fasciola and underscores its importance as a fascinating and ecologically significant species in freshwater ecosystems.
