Ammonia is likely to be the primary nitrogenous waste in living conditions that include <u>lots of fresh water flowing the gills of a fish</u>.
Nitrogenous wastes within the frame generally tend to form toxic ammonia, which need to be excreted. Mammals which includes humans excrete urea, even as birds, reptiles, and a few terrestrial invertebrates produce uric acid as waste.
Aquatic animals in general excrete ammonia. Ammonia is a small molecule that conveniently diffuses throughout skin and gills if enough water is available, however the kidneys inefficiently excrete ammonia. Ammonia is exceedingly toxic, and animals cannot continue to exist even mild ammonia concentrations in their frame fluids.
As a result, the marine organisms excrete ammonia without delay into the water and are referred to as ammonotelic. Ammonotelic animals consist of crustaceans, platyhelminths, cnidarians, poriferans, echinoderms, and other aquatic invertebrates.
