Ecology: This large snail is found in freshwater lakes, rivers, streams, ponds and ditches, preferring slow-moving water. The snails identified in Pasco County look different from the ones previously seen in Miami-Dade County: Their flesh is creamy white, rather than grayish brown. Maiden Campeloma Radula with tricuspid lateral teeth (Fig. Aquatic; moves by gliding motion. It should also be remembered that many groups have not been studied sufficiently, and the reader may have material that adds to or contradicts previously recorded information. 11).
