Osmoconformer and Osmoregulators. Marine water and Fresh water

Osmoregulation in marine water animals is crucial to maintain the balance of salt and water across their membranes.
Here are some ways different marine animals achieve this
Isotonicity with seawater:
Most marine invertebrates are isotonic with seawater, which means their body fluid concentrations adjust to changes in seawater concentration.
Electrolyte balance:
Some fish achieve electrolyte balance by actively transporting salts through their gills. When they move to a hypertonic marine environment, they excrete excess salts through their gills and urine.
Ureotelic process:
Cartilaginous fish like sharks achieve isotonicity by storing high concentrations of urea in their bodies. They also have a rectal gland that helps to secrete salt.
