Habitats and Predators

Freshwater mussels

Freshwater mussels filter water in through an inhalant aperture and expel water through an exhalant aperture (both visible in these mussels). Mussels often are partially to mostly buried within substrate with only the posterior end of the mussel visible (the end where filtering occurs). In this photo, a brook floater mussel and triangle floater mussel are actively filtering. Photo by E. Nedeau



Muskrats are a common predator

of freshwater mussels.
