Abstract The functional morphology of the alimentary canal, particularly the stomach, of Donax venustus Poli and D. semistriatus Poli has been investigated. The stomach in both species belongs to type V as defined by Purchon (1960). There is a right caecum into which open ducts from the digestive diverticula on the right side of the stomach. In Donax venustus and D. semistriatus there is a posterior typhlosole inside the coiled section of the mid-gut. Also present are three teeth in the gastric shield and a sorting area inside the dorsal hood. The morphological similarity of the alimentary canal, together with the presence of intermediate morphotypes between the shells of the two species, raises questions concerning their taxonomic positions, which must be resolved by future investigations using different criteria. The evolution of the stomach in the Donacidae is discussed. All data in the Integrated Marine Information System (IMIS) is subject to the VLIZ privacy policy  Top | Authors
