Abstract
    The study of the comparative anatomy of the experimental asteroids' digestive tract puts the accent on the great morphologic variation of the digestive tract according to the spp considered. The relations between pyloric stomach and pyloric canals are subjected to important modifications, such as the size of the cardiac stomach. The authors describe a 'superior stomacal complex' a very special organ observed in 3 starfish spp supposed microphagous. The alkaline phosphatase has been titrated in all the digestive organs. The pyloric caeca show a rather strong activity, but the activity is most important at the level of 'superior stomacal complex'. The Tiedemann pouches present very little alkaline phosphatase.
