In fishes ammonium ions are excreted through
WebJul 8, 2024 · Excretion Animals need to excrete because they take in substances that are excess to the body’s requirements and many of the chemical reactions in the body produce waste products. If these substances were not removed they would poison cells or slow down metabolism. All animals therefore have some means of getting rid of these wastes. WebTherefore, ammonia excretion is most common in aquatic species. Many invertebrates release ammonia across the whole body surface. In fishes, most of the ammonia is lost as ammonium ions (NH4+) at the gill epithelium. Freshwater fishes are able to exchange NH4+ for Na+ from the environment, which helps maintain Na+ concentrations in body fluids.
