The pinacoderm is the outer most layer of cells (pinacocytes) in the phylum Porifera (sponges), equivalent to the epidermis in other organisms.
The pinacocytes are on the external surface of the sponge body and characterized as an epithelial layer of flattened cells. (General Zoology Laboratory Guide, Fourteenth Edition: by Charles F. Lytle and John R. Meyer, 2005)
