Conchology (from Ancient Greek: κόγχος konkhos, "cockle") is the study of mollusc shells. Conchology is one part of malacology, the study of molluscs; in any case, malacology is the study of molluscs as entire life forms, while conchology is limited to the study of their shells. It incorporates the study of land and freshwater mollusc shells and in addition seashells and stretches out to the study of a gastropod's operculum.
Conchology is presently now and then observed as an ancient study, on the grounds that depending on just a single part of a life form's morphology can be deluding. Be that as it may, a shell regularly gives in any event some knowledge into molluscan scientific classification, and generally the shell was frequently the main piece of extraordinary species that was accessible for study. Indeed, even in current historical center accumulations usually for the dry material (shells) to incredibly surpass the measure of material that is protected entire in liquor.
Conchologists essentially manage four molluscan orders: the gastropods (snails), bivalves (mollusks), Polyplacophora (chitons) and Scaphopoda (tusk shells). Cephalopods just have little inside shells, except for the Nautiloidea. A few gatherings, for example, the ocean slug nudibranchs, have lost their shells by and large, while in others it has been supplanted by a protein bolster structure.
