%X Ocean temperatures in the Gulf of Mexico are predicted to increase by 2oC by 2050, and over the next 100 years, global warming is expected to cause additional increases by as much as 2oC to 4oC. In this study, pigment concentrations were used to determine the effects of temperature and salinity stress on the sponge Cliona celata. Pigments extracted from sponge tissue were analyzed using HPLC; no significant losses in pigments occurred at temperatures of 18oC, 25oC, 31oC, and 33oC and practical salinities of 22, 32, and 42, indicating a high threshold to thermal and salinity stresses. Further, we report for the first time the existence of this species in the jetties of Texas, representing a new range in habitat. These sponges may become more dominant in reef habitats and may rapidly colonize new locations as corals worldwide suffer from bleaching.
