Abstract
Changes in salinity tolerance were determined during metamorphosis in Lampetra tridentata. Lampreys in Phase 5 of metamorphosis were unable to withstand salinities>13.4‰S, while those in Phase 6 survived direct transfer to sea water (30‰S). This abrupt change in tolerance coincided with the opening of the foregut lumen. Parasitic feeding began at the end of Phase 7 of metamorphosis following the completion of tooth development.
