Nitrogenous wastes, formed by the breakdown of proteins and nucleic acids (both contain nitrogen in their structure) tend to form toxic ammonia.

So, only aquatic animals tend to release ammonia into the water (terrestrial animals release urea or ureic acid). Animals that excrete ammonia are said to be ammonotelic.
