Volume regulation in tetraphyllidean larvae

  • Published:
Proceedings / Indian Academy of Sciences

Summary

The tetraphyllidean larvae increased in volume, when transferred to dilute sea-water. However there is a decrease in volume in 50% sea-water. The conductivity of the medium shows a slight decrease both in 50% and 25% sea-water, indicating the uptake of salts from the external medium. In 10% sea-water the conductivity of the medium goes up steadily.
