» Life History
Suitable habitat for this species include free-flowing streams with a variety of flow regimes and water depths. The James spinymussel is found in a variety of substrates that are free from silt.
Like other freshwater mussels, this species is a filter feeder. It feeds on plankton collected from water that is passed over its gills.
Reproduction occurs sexually. Females carry eggs in their gills. During spawning, the male releases sperm into the water column and the sperm is taken into the female through the gills. The resulting larvae (known as glochidia) are released from the female into the water column and must attach to a fish host, development of glochidia continues. Once metamorphosis is complete, the juvenile mussel drops off the fish host and continues to develop on the stream bottom. Known fish hosts for this species include the bluehead chub (Nocomis leptocephalus), rosyside dace (Clinostomus funduloides), blacknose dace (Rhinichthys atratulus), mountain redbelly dace (Phoxinus oreas), rosefin shiner (Lythrurus ardens), satinfin shiner (Cyprinella analostana), central stoneroller (Campostoma anomalum), and swallowtail shiner (Notropis procne).
