Quick Summary

A solenocyte is a specialized, flagellated cell found in the nephridia of certain aquatic animals, including some annelids, mollusks, and lancelets. These cells are part of the excretory system, functioning to filter waste products from the body fluids. The term "solenocyte" is derived from Greek words meaning "tube" and "cell," referring to its tubular structure and cellular nature. These cells play a crucial role in osmoregulation, helping these organisms maintain a stable internal environment, particularly in aquatic settings where salinity can vary.12
