Malacology is the study of mollusks. This includes animals like octopus, snails, slugs, and clams. It is the second largest phylum of animals, making them one of the most successful groups on the planet. There are over 80,000 described species of mollusks with many more left to be discovered. Mullusca is composed of 8 recognized classes including Cephalopoda, Gastropoda, Polyplacophora, Scaphapoda, Monoplacophorans, the Aplacophorans, Caudofoveata and Solenogastres, and Bivalvia.

0 to 0 meters
Marine, Brackish, Terrestrial; Mangrove swamps and salt marshes on shore and in the water
This is the most common salt-marsh snail on the United States east coast. These snails can be found climbing to the top of marsh grasses as the tide ries to avoid the water as much as possible. They seem to be a favorite food of salt-marsh ducks.
