- Enantiostasis and estuarine organisms
- estuarine environment
- Huge fluctuations in salt and water concentrations
- The maintenance of physiological and metabolic FUNCTIONS in response to variations in the environment
- 2 strategies
- 1.Osmoconformers
- Tolerate the changes in salinity
- Alter their internal concentrations to MATCH the external environment
- Use amino acids to control osmotic pressures
- SHARKS / FIDDLER CRABS
- Alter their internal concentrations to MATCH the external environment
- Tolerate the changes in salinity
- 2.Osmoregulators
- Avoid changes in salinity in their internal environment
- Exclude salt to keep fluid concentration constant
- Mussels close their valves
- Produce dilute urine
- Salmon can adapt to both salt and fresh water environments
- Exclude salt to keep fluid concentration constant
- Avoid changes in salinity in their internal environment
