Euryhaline organisms are able to adapt to a wide range of salinities. An example of a euryhaline fish is the molly, Poecilia sp., which can live in fresh, brackish, or salt water. The European shore crab Carcinus maenas is an example of a euryhaline invertebrate. Euryhaline organisms are commonly found in habitats such as estuaries and tide pools where the salinity changes regularly. However, some organisms are euryhaline because their life cycle involves migration between freshwater and marine environments, as is the case with salmon and eels. Poecilia sphenops is a species of fish, of the genus Poecilia, known under the Common Name Molly. ... For the village on the Isle of Wight, see Freshwater, Isle of Wight. ... Brackish water is water that is saltier than fresh water, but not as salty as sea water. ... Sea water is water from a sea or ocean. ... Binomial name Carcinus maenas (Linnaeus, 1758) Carcinus maenas (the (European) green crab, (European) shore crab or common shore crab) is a common littoral crab native to European and North African coasts as far as the Baltic Sea in the east, and Iceland and central Norway in the north. ... An estuary is a semi-enclosed coastal body of water which has a free connection with the open sea and within which sea water mixes with fresh water. ... Tide pools (also tidal pools or rock pools) are rocky pools by oceans that are filled with seawater. ...

The opposite of euryhaline organisms are stenohaline ones, which can only survive within a narrow range of salinities. Most freshwater organisms are stenohaline, and will die in sea water, and similarly most marine organisms are stenohaline, and cannot live in fresh water.

To identify the molecular components involved in body fluid homeostasis, the change of expression of each gene during adaptation of euryhaline fishes to different salinities is a potential useful marker since the genes involved are expected to be drastically up- or down-regulated during the adaptation.
In general, the largest difference between FW fish and glomerular SW fish regarding structure of the renal tubules is the presence or absence of a distal segment, which acts as a urine-diluting segment in FW fish [30].
Most of the euryhaline fish have a FW-fish type of nephron such as the European eel (Anguilla vulgaris), Pacific pink salmon (Oncorhynchus gorbuscha), rainbow trout (Oncorhynchus mykiss), southern flounder (Paralichthys lethostigma), armored sculpin (Leptocottus armatus), medaka (Oryzias latipes), and spotted green pufferfish [20,30].
Four strains of euryhaline bacteria belonging to the genus Halomonas were tested for their response to a range of temperatures (2, 13, and 30°C), hydrostatic pressures (0.1, 7.5, 15, 25, 35, 45, and 55 MPa), and salinities (4, 11, and 17% total salts).
An elevated salinity was previously shown to increase the maximum hydrostatic pressure for growth in the psychrophiles Moritella marina (54, 73) and Streptococcus faecalis (reclassified as Enterococcus faecalis [63]) (36) and to decrease the piezosensitivity of Escherichia coli to an extremely high hydrostatic pressure of 270 MPa (25).
Consistent with previous studies of Halomonas strains and other moderately halophilic and euryhaline species (41, 42, 44, 51, 74, 77), the proportion of MUFA decreased in concentration (and the proportion of saturated fatty acids concomitantly increased in concentration) with increased salinity, as was observed with H.
