In animals the main excretoy products are CO2 and nitrogenous waste like ammonia, urea, uric acid. Carbon dioxide and water are produced during tissue respiration. Nitrogenous compounds are formed from the breakdown of proteins and amino acids.

Protozoans, crustaceans, platyhelminthis, cnidarians, poriferans, echinoderms,freshwater fishes, larvae / tadpoles of amphibians are ammonotelic (excrete ammonia).

Ureotelic organisms include cartilaginous fish, few bony fishes, adult amphibians and mammals including humans. Urea is less toxic as compared to ammonia.

The uricotelic organism excretes uric acid which is least toxic and least soluble in water.Examples are terrestrial arthropods (including insects), lizards, snakes, and birds.
