The stomach of the South American marsupial family Caenolestidae has a gland on its lesser curvature around the cardia. This cardiogastric gland is bi-lobed, typically 11 × 5 mm and bears a distinctive, highly folded mucosa which forms sac-like invaginations. These open into the stomach lumen via 40-60 slit-like orifices. The gland mucosa contains unbranched gastric glands which are considerably longer than those of other gastric glands present elsewhere in the stomach. The cells within the cardiogastric gland show intense eosinophilic staining properties, with the parietal cells being larger than those found in other regions of the stomach, as well as being arranged in clusters. Argentaffin cells are not present in the stomach mucosa. The gross morphology of the stomach and intestine is similar to that found in small carnivorous marsupials.
