Abstract: 
Ultrafiltration could be the 1st step in urine formation in Sepia officinalis and Octopus vulgaris. The organization of the podocytes indicates that ultrafiltration can occure through these cells. They have a thick basal lamina in contact with the peripheral blood lacunae and the cell apices lie in infoldings of the lumen of the appendage. Comparison between the colloid-osmotic and the hydrostatic pressures of the fluids in the branchial heart and the pericardial coelom shows that an ultrafiltration can take place during the branchial heart systole and during a long phase of the diastole. Comparison of the osmolalities of blood, coelomic fluid, renal sac fluid and sea-water shows that these species are hypoosmotic regulators.
