When it comes to fishkeeping, Urea is near enough to Ammonia to be treated the same way. They both are deadly poisons to the fish and have to be made safe naturaly by the use of Bacteria in a filter. Elasmobranches, such as sharks, primarily live in seawater and are able to produce urea as well as ammonia. This is important for osmoregulation, as said earlier the hypertonic seawater means water is able to leave bodily fluids by osmosis. Sharks do have to deal with a slight influx of salt, which is excreted by a rectal gland. One of the ions that sharks use is urea. Urea is relatively easy to produce (most organisms already make it in some form, they just excrete it), and works just fine as an ion from an osmotic perspective. Ammonia is toxic, as mentioned by Anil, and it requires much water to remove from organism so it's produced primarily by water organisms which are not constraint by lack of water. Urea is less toxic and requires less water to remove from organism (so it's better in terrestrial environment) but it requires more energy to produce.
