Euryhaline species denotes an animal

  • without osmoregulation

  • which lives in saline water

  • which has a wide range of saline tolerance

  • which has a wide range of temperature tolerance

Solution

C.

which has a wide range of saline tolerance

Euryhaline organisms are able to adapt to a wide range of salinities.  These organisms are commonly found in habitats such as estuaries and tide pools where the salinity changes regularly.

Example, the green crab is a euryhaline invertebrate that can live in salt and brakish water. Molly or Poecilia sphenops is an example of euryhaline fish that lives in fresh or brackish or salty water.
