What distinguishes Euryhaline organisms from stenohaline organisms?
- Salinity Tolerance Classifications:
- Euryhaline Organisms: Aquatic organisms possessing robust physiological and cellular osmoregulatory adaptations that enable them to tolerate a wide range of ambient salinities (e.g., Milkfish Chanos chanos, Barramundi Lates calcarifer, Tilapia Oreochromis mossambicus, Mullet Mugil cephalus).
- Stenohaline Organisms: Organisms that can survive only within a narrow, restricted salinity range, lacking the osmoregulatory flexibility to withstand salinity shifts (e.g., pure freshwater carps or stenohaline reef corals).
- Correct Option: Option 3 (Euryhaline organisms can adapt to a wide range of salinities, while stenohaline organisms can only tolerate narrow ranges).
