Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.
Osmoregulators
Osmoregulators are either marine or freshwater organisms that tightly regulate their internal osmolarity in a constant value. Moreover, their osmolarity does not depend on the osmolarity of the external environment. Osmoregulators are the commonest type of aquatic animals. Generally, osmoregulators in freshwater actively uptake salts through their gills. Therefore, water diffuses into their body through the body wall. The excess water can also be expelled from the body through the production of a lot of very dilute urine.
In contrast, marine osmoregulators have a lower internal osmotic concentration than that of the external environment. Therefore, they actively expel salts from their gills.
Osmoconformers
Osmoconformers are exclusively marine organisms that match their internal osmolarity to the osmolarity of the outside environment. However, their ionic composition may be different from that of the outside seawater. Their internal environment is isotonic to the external environment. Generally, most marine invertebrates are osmoconformers.

Most welcom

[@alessonwithkuntal7436]

Freshwater invertebrates ke liye isotonic kaise rakhega ?

[@JiyasBiologyTutorials]

Fresh water invertebrates cannot survive in isotonic
