On the basis of nitrogenous metabolic waste the animal are of four types:
(i) Ammonotelic: Excreted ammonia, e.g., aquatic animals, bony fishes, frog, toad and crocodile, etc.
(ii) Aminotelic Excreted amino acid, e.g., Mollusca and echinoderms.
(iii) Ureotelic Excreted urea, e.g., frog, toad and mammals.
(iv) Uricotelic  Excreted uric acid, e.g., insects, land reptiles and birds.
