title: Observations on the morphology and histochemistry of the midgut and hindgut of Portunus sanguinolentus (Herbst) (Crustaceans: Brachyura).
abstract: The midgut of Portunus sanguinolentus comprises the intestine, the anterior and posterior midgut caeca and the hepatopancreas. The hindgut comprises the rectum, which continues to the anus, a slit-like opening on the ventral surface of the telson. The limits of the midgut and hindgut are specified. The midgut has no cuticle, whereas the hindgut is lined with a cuticle composed of an outer keratin and an inner collagen layer. Four types of cells--E,R,F, and B--were differentiated in the hepatopancreas. Histochemically, the hepatopancreas contains moderate amounts of glycogen and large quantities of lipids and proteins, but no mucopolysaccharides.
