Conchology is the scientific study of shells and mollusks, which are soft-bodied animals that often have hard, protective outer shells. This field focuses on the classification, structure, and function of shells, as well as the ecological roles of the organisms that produce them. Conchologists often collect and analyze shells to understand biodiversity and evolutionary relationships among different species. The study of conchology can also involve examining the fossilized remains of shells, providing insights into past environments and climate changes. Conchologists may contribute to conservation efforts by studying endangered marine species and their habitats, helping to protect these vital ecosystems.
