Abstract: The cnidarian Anthopleura elegantissima is subject to a wide variety of external stresses. The effects of decreased salinity were examined in the field and in a laboratory environment. Animals were experimentally subjected to decreased salinities of 10 ppt, 17ppt, and 25 ppt over a period of 4 days. Laboratory results suggest that salinity stress induces algal cell loss, however, cell loss was not observed in the field. Mechanisms of release active in bleaching under salinity stress appear to result in the release of free algae.
