Osmoregulation in Animals | Osmoregulators and Osmoconformers Class 12 Biology Chapter 15
The maintenance of constant osmotic conditions (water and solute concentration) in the body is called osmoregulation. Animals may be either osmoregulators or osmoconformers with respect to their external environment.
Those animals that can maintain internal osmotic concentrations different from the surrounding medium are called osmoregulators. Such animals are hypotonic or hypertonic to their environment. Almost all of the freshwater animals and most of the marine vertebrates are osmoregulators.
Those animals that change the osmotic concentrations of the body fluids according to that of surrounding medium are called osmoconformers. These are isotonic to their external environment. These include all marine invertebrates, some freshwater invertebrates and some marine vertebrates like Myxine (hag fishes) and elasmobranches (sharks and rays).
