Euryhaline

Eurihaline organisms are those aquatic beings that are capable of living in waters that have a wide range of salt concentrations (for example, in a river upstream and near the mouth) without Your metabolism is affected. To do this, they use salinity regulation systems, such as the lacrimal glands, the nostrils, etc. They try to have a saline concentration similar to that of the fluid (water).

An example of euryhaline fish are salmon, which are capable of living in the sea (an environment with a very high saline concentration: 37 g of salt per liter of water) and in the fresh water of a mountain river, when They go up to spawn in the clean and cold waters. Other euryhaline organisms are eels and brine shrimp.
