Osmoregulation inClibanarius padavensis de man, under heterosmotic conditions

  • Published:
Proceedings / Indian Academy of Sciences

Summary

1.C. padavensis can tolerate wide salinity variations of 1·2‰ to 34‰.

2. Survival rate is maximum in 75% to 25% sea-water, inC. padavensis.

3.C. padavensis maintains its body fluid hypotonic in sea-water and hypertonic in 25% sea-water and further dilutions. Isotonicity between the external medium and body fluid is established in 50% sea-water.

4. The chloride level of the body fluid is maintained more or less constant both in sea-water and distilled water.

5. The actual mechanism of regulation is not yet known, but it is probably by an active retention of chlorides in the body by the animal, coupled with differential permeability of the body surface.
