The opisthobranchs’ digestive system is characterized by the presence of an oral muscular mass containing the radula and a labial armor. The radula is a chitinous teeth ribbon that is used for food in various ways. The shape or the radula varies greatly among opisthobranch species and it is generally a good distinctive character among species.<\/p>\n

The buccal mass is normally connected to a pair of salivary glands and the esophagus. The esophagus in many opisthobranch groups has a bag with numerous chitinous plates. The esophagus is connected to the intestine through the stomach, which is a more or less extensive area which joins with the digestive gland. In some groups, there is a blind tract that connects the esophagus and the stomach.<\/p>\n

The circulatory system of opisthobranchs molluscs is open, as in the rest of the molluscs, and the blood circulation is partly produced by a two-chamber heart and body movement.<\/p>\n

The nervous system of opisthobranchs is composed by ganglia ring located around the anterior side of esophagus, joined together by connective tissue.<\/p>\n
