In birds, on the other hand, the kidneys, lower intestine, and, in some species, salt glands all play important roles in osmoregulation. Water balance requires the input matches output. Most birds can obtain water directly by drinking.
Many marine animals are isotonic with their saltwater environment. Their body fluids are about 1000 mosm/L in concentration. Their body fluids are about 1000 mosm/L in concentration. Osmoregulators are animals which must constantly adjust their body fluids by active transportation.
In the marine environment, the vast majority of organisms are osmoconformers, meaning that all of their bodily fluids are in osmotic equilibrium with the surrounding seawater. If the salinity of the seawater should vary due to local precipitation or evaporation, the osmotic concentration of the organism’s body fluids vary in concert with the

Water that is consumed in food or actively drunk is called preformed water. Compared to terrestrial mammals, marine mammals consume a water rich diet of fish and marine inverte brates (70–80% water). Prey contains electrolytes and
Even though most marine mammals live in an aquatic medium, the animals’ internal fluid composition differs from the ambient environment and therefore requires active processes to maintain it. Osmoregulation describes the way in which the internal water and electrolyte concentration of this internal environment is maintained.
Osmoregulation in marine mammals has been investigated for over a century; however, a review of recent advances in our understanding of water and electrolyte balance and of renal function in marine mammals is warranted.
Many animals need to control the water content of their body because the concentration of their body fluids is different to that of their environment. The process by which the amount of water and concentration of soluble ions in the body are regulated is called osmoregulation. In most cases the organs which are responsible for osmoregulation are also involved in the excretion of metabolic
Osmoregulation is the control of the levels of water and mineral salts in the blood. It is a homeostatic mechanism. There are three important homeostatic mechanisms: osmoregulation, thermoregulation and regulation of blood sugar levels.
