The writer describes the biology of these small, inedible shell fish and then explains some of the negative effects they can have on aquatic systems. Since phytoplankton and detritus consumed by tiny animals called zooplankton which in turn are eaten by small fish and these small fish by larger fish, biologists seem concerned that zebra mussels' tendency to eat the same items could damage established food chains by removing needed energy from its bottom level.
