Detailed explanation-1: -Physiological Adaptations. Osmoregulation is an ecologically important function in nemerteans as in all other freshwater invertebrates with permeable body walls. It is controlled by the cerebral organs and involves several organs and enzymatic systems associated with blood vessels (Moore and Gibson, 1985).

Detailed explanation-2: -Osmoregulation helps in maintaining a constant normal blood pressure. It is an important component of life as it maintains water and mineral balance at the cellular level. Osmoregulation is mostly controlled by the kidneys by the hormone ADH.

Detailed explanation-3: -Osmoregulation is a homeostatic mechanism that regulates the optimum temperature of water and salts in the tissues and body fluids. It maintains the internal environment of the body through water and ionic concentration.

Detailed explanation-4: -Water content Osmoregulation is the control of water levels and mineral ions (salt) in the blood. Water levels and mineral ions in the blood are controlled to keep the concentrations the same inside the cells as around them. This protects cells by stopping too much water from entering or leaving them by osmosis.

Detailed explanation-5: -Introduction. Osmoregulation is a fundamental process of living systems, equivalent in importance to respiration, digestion, or reproduction. Osmoregulatory processes are those that enable a fish to maintain its cellular fluid composition and volume.
