N2 - Temperature tolerance (lt50) of the scavenging gastropod Nassarius festivus was determined as 22.5, 64.3 and 160 hr at temperatures of 38, 36 and 33°C, respectively. Hyposalinity tolerance (lt50) at salinities of 0, 5 and 10‰ was found to be 60, 67 and 170 hr respectively. Respiration rate was measured at combinations of four levels of temperature (20, 25, 30 and 35°C) and six levels of salinity (10, 15, 20, 25, 30 and 35‰) before and after acclimation. Temperature, salinity and their interactions were significant in affecting respiration rate of both non-acclimated and acclimated individuals. Among these, salinity has the greatest effect. Although respiration rate was increased following acclimation, the values obtained were lower than the control, indicating incomplete acclimation.
