A ureotelic organism excretes excess nitrogen as urea. It is one of the three major forms of excretion of nitrogenous waste in organisms, the others being ammonotelism and uricotelism.[1]
Urea is less toxic than the ammonia excreted by ammonotelic organisms. It requires 0.05 L of water to excrete 1 g of nitrogen, approximately only 10% of that required in ammonotelic organisms. Ureotelic organisms include cartilaginous fish, some bony fish, adult amphibians, and mammals, among others.[1] Humans can be described as being ureotelic organisms.[2]

- … A changeover from ammonotelism to ureotelism was analyzed by determining amounts of ammonia and urea excreted from normal and metamorphosis-arrested animals. … Because the transition of hemoglobin subunits in the metamorphosis-arrested larvae has been reported to occur on the same time schedule as in the controls, it is concluded that either transitions of hemoglobin subunits from larval to adult or pattern of nitrogen excretion from ammonotelism to ureotelism are independent on the morphological metamorphosis in H. …
