Question

Euryhaline species have a wide range of tolerance to :
(i) Light (ii) Temperature (iii) Salinity (iv) All of the above
​

Answer 1

Euryhaline species have a wide range of tolerance to (iii) Salinity.

Euryhaline species:

• A life form that endures many salinities is a euryhaline organic entity.
• The particular attribute of the euryhaline life form is that it can get by in saltwater, freshwater, and salty water.
• Tide pools and estuaries are home to the euryhaline life forms as the saltiness in these territories changes consistently.
• A few organic entities, notwithstanding, become euryhaline in light of the idea of their life cycle that includes development from freshwater to marine water.
• Molly fish is an illustration of a euryhaline fish since it lives in salt water, fresh water, and harsh water.
• Carcinus maenas known as the green crab is a euryhaline invertebrate that lives in harsh salt water.
• These creatures effectively keep up with their water levels through osmoregulation.

Answer 2

Euryhaline species have a wide range of tolerance to (iii) Salinity.

Euryhaline species:

• A wide variety of salinities can be tolerated by euryhaline species.
• The molly is an illustration of a euryhaline fish, which can exist in fresh, brackish, or salt water.
• A euryhaline invertebrate is one that can survive in both brackish and salt water, such as the green crab.
• Since the majority of fish are stenohaline, they cannot transition between freshwater and saltwater.
• Surprisingly, certain fish can survive in both freshwater and saltwater.
• An estimated 3 to 5 percent of all fish species are these euryhaline fish.
• While euryhaline creatures, which are found in estuaries where rivers and the sea converge, are found, are particularly tolerant of substantial fluctuations in salinity, stenohaline organisms have a low tolerance to salinity changes.
• Euryhaline creatures can tolerate temperature changes quite well.
