Abstract Arguably climate change is one of the biggest challenges faced by many organisms. One more significant these decreasing pH level ocean, a consequence increasing amount atmospheric CO 2 being absorbed. With current open ocean 8.15 projected to fall just over 7.6 in 2100, impacts could be devastating for marine species reliant upon olfaction survive. Here, we show that Carcinus maenas (shore crab) can detect and respond presence odour cues from predatory with no between both conditions. In contrast, C. ability prey altered conditions, delayed response observed at 7.6. A difference seen males females, detecting faster than females reduced pH, suggesting potential better acclimated future The chemistry postulated have fundamental impact on chemical communication systems aquatic species. such negative feeding responses , typically robust keystone intertidal confirm not all behaviours are affected equally potentially implications functional traits interactions.
