Nitrogenous waste is excreted in the form of pellet or paste by:
Updated On: May 5, 2024
- Ornithorhynchus
- Salamandra
- Hippocampus
- Pavo
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Reptiles, birds, land snails and insects excrete nitrogenous wastes as uric acid in the form of pellet or paste with a minimum loss of water and are called uricotelic animals.
Pavo (Peacock) belongs to class aves (birds). Hence, it excretes nitrogenous wastes in the form of pellets or paste.
Ornithorhynchus (Platypus) is a mammal and is ureotelic (excretes urea). Salamandra (Salamander) is an amphibian and is ammonotelic (excretes ammonia).
Hippocampus is a bony fish and is ammonotelic.

Excretory products and their elimination
The physiological process of the elimination of metabolic waste from the body is called excretion. The excretory products comprise amino acids, carbon dioxide, urea, uric acid, water, and ammonia. Some of the Molluscs and Echinoderms excrete waste products from the body in the form of amino acids. Ammonia is the foremost excretory product in animals, it is derived from the proteins exists in the food we eat.
