flame cell

a specialized cell that contains a central cavity with several beating cilia. These create a current in the tubules to which they are connected. The tubules usually open to the exterior and flame cells control the water content of the body. The flame cell and tubule is known as a protonephridium and is found in PLATYHELMINTHS, NEMERTINES, rotifers, ANNELIDS, the larvae of molluscs and AMPHIOXUS.
