Animals that can tolerate a narrow range of
salinity are
(a) stenohaline (b) euryhaline
(c) anadromous (d) catadromous

Answer 1

The animals that can tolerate narrow range of  salinity are  (a) stenohaline.

• Stenohaline describes an organism, generally a fish, that can not tolerate a wide fluctuation in water salinity.
• Stenohaline is derived from the following words: "steno," meaning narrow, and meaning salt, haline.
• Most freshwater organisms are stenohalin and die in seawater. Likewise, most marine organisms are stenohalin and can not live in fresh water.
