Malacology is the study of mollusks (snails, clams, octopods, etc.).
The Malacology Department promotes the scientific study, conservation, and acquisition of extant mollusk species including gastropods (marine, terrestrial, and freshwater snails and slugs), bivalves (marine and freshwater clams), cephalopods (octopus, squid, cuttlefish, and nautilus), polyplacophorans (chitons), scaphopods (tusk shells), aplacophorans (wormlike mollusks), and monoplacophorans (‘primitive’ limpetlike snails). The collection is worldwide in scope with an emphasis on the eastern Pacific Ocean (arctic Alaska to southern Chile) and includes an estimated 500,000 lots containing approximately 4.5 million specimens.
Malacology staff, associates, and volunteers sort, identify and verify specimen identifications, curate, rehouse, database, and incorporate specimens into the research collection. These tasks represent a huge undertaking in terms of the number of specimens incorporated into the collection annually. Malacology is active in museum programs, offering hands-on experiences with both extinct and extant mollusks and local geology.
