solenocyte In some Annelida, Platyhelminthes, Rotifera, and other invertebrates, a tubular terminal cell at the blind end of each tubule of a protonephridium (see NEPHRIDIUM). The solenocyte carries a flagellum which wafts excretory products along the tubule. The walls of the tube are thin and consist of pillar-like rods. The excretory fluid is thought to be formed by ultra-filtration of body fluids through the wall.
