Musculium argentinum is oviparous, iteroparous, and sequential incubator, reproducing throughout the year. clams and pea clams (Family Sphaeriidae), and non-native Asian clams (Cor-bicula fluminea) are much smaller than native mussels (less than one inch). Life histories and population dynamics of two populations of Musculium argentinum, one inhabiting a fluvial environment and the other a lacustrine one, are compared. Aside from obvious size differences, clams have thinner shells, different teeth morphology, mantles fused to form true siphons, and different reproductive strategies than mussels61. Heard (1965) compared the life cycles of a number of species of the genus Pisidium found in North America. johnstoni. Although the mollusks’ shell is often seen empty, during life there is a soft-bodied animal inside. Increase knowledge of the distribution and taxonomy of mollusks at Sphaeriidae may be particularly suited to meet unusual environmental conditions.
