choanocytes
pinocytes
nephrocyte

Choanocytes or collar cells are cells that line the interior of asconoid, syconoid and leuconoid body type sponges that contain a central flagellum, or undulipodia, surrounded by a collar of microvilli which are connected by a thin membrane.
Nephrocytes are the specialized cells, present in arthropods. Their main function is the accumulation or formation of waste or excretory products.
