Question

Give reasons why aquatic animals are mostly ammoniotelic in nature where as terrestrial forms

are not.​

Answer 1

Ammonia is the most toxic form and requires large amount of water for its elimination, terrestrial adaptation necessitated the production of lesser toxic nitrogenous wastes like urea and uric acid for conservation of water.

Answer 2

Answer:

many bony fishes, aquatic amphibians and aquatic insects are ammonotelic in nature. Ammonia, as its readily soluble, in water is excreted by diffusion across body surface or through gill surfaces (in fishes) as ammonium ions. It is highly soluble in water and requires large amounts of water to be lost from the body.
