What does malacology mean?
Malacology is the branch of zoology that studies molluscs, a diverse group of soft-bodied animals that includes snails, slugs, clams, mussels, oysters, scallops, squids, octopuses, and many marine and freshwater species. The field examines their anatomy, physiology, evolution, behaviour, ecology, and relationships with other organisms. Malacologists may work with living animals, preserved specimens, fossils, or collections of shells, especially when investigating classification and biodiversity. Although many people encounter molluscs as foods, pests, or aquarium animals, the discipline also addresses important questions about marine ecosystems, invasive species, and evolutionary history. The word is most often encountered in universities, museums, research publications, and organisations dedicated to the study of molluscs.

Malacology reaches beyond empty shells: it studies the anatomy, evolution, behaviour, and diversity of animals that have no bones, including octopuses, squid, and many tiny marine invertebrates.

Where does malacology come from?
The word malacology comes from the Greek malakos, meaning “soft” or “soft-bodied,” combined with the Greek suffix -logia, meaning “study of.” The term developed in the early 19th century as a scientific discipline devoted to molluscs. Its root is reflected in related English words such as mollusc, molluscan, malacologist, and malacological.
