Temperature effects on behavior and survival of marine invertebrates exposed to variations in hydrostatic pressure

Investigation into the pressure resistance of 8 intertidal species belonging to the genera, Uca, Sesurma, Talorchestia and Littorina from the Northern Gulf of Mexico and Panama sheds light on the relationships between temperature and hydrostatic-pressure resistance. Generally, increasing temperature increases the pressure required to elicit reversible reactions such as increased activity and tetany, or paralysis, wheroas increasing temperature generally evokes the irreversible response of death (LD₅₀) at a decreasing pressure. Tropical stenotherms tend to be more sensitive to hydrostatic pressure than eurythermal-temperate species at the same or similar temperatures.
