.......... Referring to animals that produce urea as their main nitrogenous excretion.

Answer 1

Ureotelic is the term referring to animals that produce urea as their main nitrogenous excretion.

Mammals, many terrestrial amphibians and marine fishes mainly excrete urea. Ammonia produced by metabolism is converted into urea in the liver of these animals and released into the blood which is filtered and excreted out by the kidneys.
