Question

What do you understand by ammonotelic, ureotelic and uricotelic animals? Give example of each.

Answer 1

Ammonotelic organisms are the organisms which excrete nitrogenous waste substances in the form of ammonia, e.g., Octopus, Sepia and bony fishes.
Uricotelic organisms are the organisms which excrete nitrogenous waste substances in the form of uric acid, e.g., Lizard, some insects and birds.

Ureotelic organisms are the organism which excretes the nitrogenous waste as urea. For example, bony fish.
