The reason because of which urea is produced in sharks and rays instead of uric acid to raise osmotic concentration of extracellular fluids. Introduction: Urea and uric acid are the excretory products that are formed by protein metabolism . Organisms according to their body requirements can either excrete uric acid or urea, both of which are less toxic than ammonia and can be stored in body for some time.
