fresh water fish
Uric acid is a nitrogenous waste that requires the least amount of water to excrete because it is mostly insoluble in water. This makes it advantageous for animals in dry environments or those with limited access to water. Examples of animals that excrete uric acid include birds and reptiles.
The nitrates in nitrogenous waste reduce the oxygen carrying capabilities of the haemoglobin in the blood of animals. Since plants do not have haemoglobin they can absorb it to help them make proteins.
Pisces fish excrete waste through their gills and kidneys. Waste products such as ammonia are released into the water through their gills, while the kidneys help filter out and excrete other waste materials.
decomposers
Most fish excrete nitrogenous waste in the form of ammonia. Ammonia is highly toxic, but fish eliminate it primarily through the gills and some through the urine. Some fish species, particularly those living in environments with low water availability, convert ammonia to a less toxic form, such as urea or uric acid, before excreting it.
Tadpoles excrete ammonia and frogs excrete urea

They've lost the subsequent enzymes required for catalyzing the synthesis of urea into ammonia.
Neither marine nor freshwater fish excrete urine or urea; both marine and freshwater fish excrete nitrogenous waste products as pure ammonia.
Animals that excrete in the form of urea nitrogenous waste derived from amino-acid catabolism
Animals excrete a variety of substances through the excretory and respiratory systems. Three things they excrete are carbon dioxide, uric acid, and ammonia.
The urinary system excretes nitrogenous wastes. The lungs excrete carbon dioxide.
The nitrates in nitrogenous waste reduce the oxygen carrying capabilities of the haemoglobin in the blood of animals. Since plants do not have haemoglobin they can absorb it to help them make proteins.

No, swordfish do not excrete through their skin. They primarily excrete waste through their kidneys and gills, similar to other fish. The kidneys filter waste products from the bloodstream, while the gills help eliminate ammonia and other nitrogenous wastes.
