Abstract
The histomorphology and histochemistry of the digestive apparatus of Murex brandaris and Trunculariopsis trunculus has been studied in order to clarify the structural features of the digestive tract and the physiology of digestion in these species. Biochemical analyses of polar lipids and of some enzymatic activities were also carried out on the connected glands. (salivary, "framboisé", Leiblein and digestive). Digestive enzyme production is not present in the stomach and intestine. These enzymes are produced not only by the connected glands, but also by a specialized epithelial cell type (granular cell) present in the oesophagus and in the rectum. Absorbtion activity is demonstrable at the level of the rectum.
