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]
