	abstract = {<p>To date, no published study has assessed the full physiological scope of a marine invertebrate species with respect to both temperature and hydrostatic pressure. In this study, adult specimens of the shallow-water shrimp species Palaemonetes varians were subjected to a temperature/pressure regime from 5 to 30{\textdegree}C and from 0.1 to 30 MPa. The rate of oxygen consumption and behaviour in response to varying temperature/pressure combinations were assessed. Rates of oxygen consumption were primarily affected by temperature. Low rates of oxygen consumption were observed at 5 and 10{\textdegree}C across all pressures and were not statistically distinct (P=0.639). From 10 to 30{\textdegree}C, the rate of oxygen consumption increased with temperature; this increase was statistically significant (P\&lt;0.001). Palaemonetes varians showed an increasing sensitivity to pressure with decreasing temperature; however, shrimp were capable of tolerating hydrostatic pressures found outside their normal bathymetric distribution at all temperatures. {\textquoteright}Loss of equilibrium{\textquoteright} (LOE) in >=50\% of individuals was observed at 11 MPa at 5{\textdegree}C, 15 MPa at 10{\textdegree}C, 20 MPa at 20{\textdegree}C and 21 MPa at 30{\textdegree}C. From 5 to 20{\textdegree}C, mean levels of LOE decreased with temperature; this was significant (P\&lt;0.001). Low mean levels of LOE were observed at 20 and 30{\textdegree}C and were not distinct (P=0.985). The physiological capability of P. varians to tolerate a wide range of temperatures and significant hydrostatic pressure is discussed.</p>
