The diffusional water permeability of the isolated mantle tissue from a series of marine, and one freshwater, species of lamellibranch molluscs was determined. The water permeability of the mantle tissue was generaly correlated with the habitat of the organism, permeability decreasing with increasing height above the sublittoral zone. Evidence is presented that a given intertidal lamellibranch species, Mytilus edulis, is capable of altering its tissue water permeability when presented with changes in external osmolality. The observed differences in tissue water permeability from different animals are not due to change in the physical dimensions of the tissue, but may be the result of changes in the chemical composition of the tissue.
