    The buccal mass is the first part of the digestive system, and consists of the mouth and pharynx. The mouth includes a radula, and in most cases, also a pair of jaws.

    Turris brevicanalis is a carnivorous snail that feeds on small crustaceans, worms, and other mollusks. It uses its radula, a toothed ribbon-like organ, to drill holes in the shells of its prey and inject venom. The venom of Turris brevicanalis is composed of various peptides, some of which have potential applications in medicine. [2]
