✦ Synopsis
The combination of phase contrast photomicrography with a method for phase contrast observation of living sponges facilitated the initial photographic record of spongillid porocyte cellular behavior. Porocytes of Corvomeyenia carolinensis HARRISON (Spongillidae) exhibit true intracellular pores and are components of the incurrent system. The number of porocyte contractile vacuoles increases during pore dilation. This increase is possibly related to an increase in the amount of cell surface in contact with the hypotonic aqueous environment. The porocyte cell type appears closely related to, and is likely derived morphogenetically from, pinacocytes of the upper pinacoderm.
