Gastrodermis (from Ancient Greek: γαστήρ, gastḗr, "stomach"; δέρμα, dérma, "skin") is the inner layer of cells that serves as a lining membrane of the gastrovascular cavity in cnidarians.[1] It is distinct from the outer epidermis and the inner dermis and is primarily associated with the ventral side of cnidarians. It is composed of specialized cells responsible for several vital physiological processes. The term is also used for the analogous inner epithelial layer of ctenophores.[2]
