(ecology)
Pertaining to the ability of marine organisms to tolerate a wide range of saline conditions, and therefore a wide variation of osmotic pressure, in the environment.

For the euryhaline species, when facing the diluted seawater, hemolymph osmoregulation is very important for the effective NaCl uptake and retention; whereas the gill epithelium cells play important roles in NaCl excretion when facing the hypertonic seawater.
In addition, other studies have reported the euryhaline character in the larval (Carvalho et al, 2013) and adult forms (Coelho, 1963, 1964), eurythermic characteristics (Stilman & Somero, 2000), and the use of different strategies by the species.
Salinity tolerance studies on rotifers have concentrated on selected euryhaline species such as Brachionus plicatilis and Brachionus rotundiformis, because of their role as starter food in mariculture for larval stages of fish and crustaceans (Snell 1986, James and Abu-Rezeq 1990).
The white shrimp Litopenaeus vannamei is a euryhaline decapod species and is generally considered an osmoconformer (Dali et al.
5%) was also found in areas with water temperatures associated with SAAMW, and its abundance in low-salinity interior waters suggests a marked euryhaline nature.
On the basis of this observation, it has been inferred that euryhaline organisms show an increase and stenohaline organisms show a decrease in respiratory parameters, but this hypothesis had been difficult to substantiate (Wheatly, 1988).
In euryhaline fish, the glomerular filtration rate and urine flow changes in the direction of ion concentrations, which means that it passes from a lower saline ion concentration to a higher one and vice versa.

This limited tolerance to low salinities can be explained by the euryhaline habits of this species, which has a natural distribution in more saline regions (Brito et al.
plicatilis density and salinity, in Period II, it is hard to explain its influence, considering that this rotifer species is euryhaline, surviving in salinities ranging from 1 to 97 [per thousand] (Walker 1981).
