Book covers all the species of Mollusca found so far in Polish waters, i.e. 63 species of Gastropoda (54 freshwater, 9 marine) and 47 species of Bivalvia (37 freshwater, 10 marine).   Individuals of many unionid species live to be 20 to 30 years of age, with some reaching 50 years or more. Annular rings on the outside of the shell can be counted to estimate a mussel’s age. The life cycle of unionid mussels illustratesUnionid mussels and pea clams are native to the interconnected nature of species in an ://   To completely eliminate unionid mussels from a pond, drain the pond completely and leave it dry for several weeks. Invasive Mollusks—Zebra Mussels and Corbicula (Asiatic Clams) The two other groups of freshwater clams are nonnative, invasive species that have caused billions of   freshwater, and terrestrial habitats. Ab living fossil species have been described and more may be discovered, as researchers survey remote areas. Colorado is home to over 40 species of native aquatic mollusks.
