Question

What is the MOST LIKELY reason for this decline in aquatic species in Virginia's Southern Watershed?

Answer 1

Six hundred fifty different species of snails are widely distributed across the streams, rivers, and lakes of North America. There are unique species associated with every type of aquatic habitat from the Canadian Arctic to the Everglades of Florida. However, the greatest species richness is associated with flowing waters (streams and rivers). The number of North American freshwater gastropods (one or no-shell mollusks) is the richest in the world, rivaled only by the river systems of Southeast Asia. North American freshwater snails represent a rich natural heritage of global importance. Freshwater snails are also an important food source for many fish, turtles, and other species of wildlife. Finally, because of their sensitivity to certain chemicals, many species are excellent water-quality indicators.
