A ureotelic organism is one whose main way to excrete excess nitrogen is via urea. Ureotelism 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 (including humans[2]), among others.[1]
