Abstract
Phase-contrast and EM investigations of the pancreatic appendages of the ductus hepatopancreas in Sepioidea (Sepia officinalis L., S. elegans d''Orb., Sepietta obscura Naef, Sepiola robusta Naef) of different age groups (newly hatched, juvenile and adult animals) showed a basic conformity in arrangement and ultrastructure. The appendages were composed of 2 epithelia, separated by a blood sinus. They had a similar polar structure marked by a brush border, a basal folded labyrinth, a high content of mitochondria and dense bodies. The differences in the structure of both cellular layers and their morphological changes, related to age and nourishment, suggested that the inner epithelium lining the duct had a dual function, serving excretion and nutrient absorption. The rather flat outer epithelium which faced the renal cavity, could be associated mainly with processes of osmoregulation and urine formation.
