The northern propellerclam is a sexed species, having both males and females. Its reproduction happens ”on the fly”, meaning that the females release a large number of eggs, which are then fertilized in the water column by the sperm released by the males, thus requiring a certain density of conspecifics for reproduction to be effective.
Growth is relatively rapid up to the age of 20, after which it slows down.
