Differentiate between Osmoconformers and Osmoregulators

(i)  Osmoconformers : 

Those organisms in which osmotic potential of body fluid fluctuates with environment called osmoconformers .
In osmoconformers, the body fluid remains isotonic to the external environment even in massive (sea water) environment.

(ii)  Osmoregulators : 

Those organisms which are capable of controlling internal osmotic potential and keeping it constant inspite of environment variations, are called osmoregulators. 
In other words, for regulation of internal osmotic balance, discharge of water in hypotonic condition of salts in hypertonic condition.
