Tentacles of Condylactis gigantea were exposed successively to H2O?NaASW dilutions, isosmotic 1 mol/l MgSO4?NaASW mixtures and returned to H2O?NaASW dilutions to explore the possible isotonicity of isosmotic MgSO4 and the reversibility of the effects of this solution on the ionosmotic characteristics of the tentacles.
