Malacology

Study of molluscs

Malacology, from Ancient Greek μαλακός (malakós), meaning "soft", and λόγος (lógos), meaning "study", is the branch of invertebrate zoology that deals with the study of the Mollusca (molluscs or mollusks), the second-largest phylum of animals in terms of described species after the arthropods. Mollusks include snails and slugs, clams, and cephalopods, along with numerous other kinds, many of which have shells. Fields within malacological research include studies of mollusk taxonomy, ecology and evolution.
