What does malacologist mean?
A malacologist is a scientist who studies mollusks, a diverse group that includes snails, slugs, clams, mussels, squid, octopuses, and many marine and freshwater species. The discipline is called malacology and combines the observation of living organisms with the study of their anatomy, evolution, behavior, distribution, and fossil remains. Malacologists may specialize in particular groups, habitats, or scientific methods, such as taxonomy, ecology, or paleontology. Shells often provide visible evidence of mollusks’ identities and histories, but the subject extends beyond shell collecting to the animals’ complete biology. The term is relatively uncommon outside scientific and natural-history contexts and is more precise than the general label “scientist,” while differing from “conchologist,” which places greater emphasis on shells.

Where does malacologist come from?
Malacologist derives from malacology, formed from Greek malakos, meaning “soft,” and -logia, meaning “the study of.” The naming reflects the traditionally soft-bodied character of mollusks. The related English words mollusc, mollusk, and molluscan come through Latin forms based on molluscus, “soft,” and correspond to the same biological group.
