In general, fish living in high-flow from changes in species interactions. Therefore, it is critical to habitats (e.g., river rapids) tend to have more streamlined bodies and understand the mechanisms by which thermal stress is transducedfins designed for steady swimming, while fish from low-flow, through behavioral interactions. The porcelain crab Petrolisthes structurally complex habitats (e.g., swamps) tend to be maneuverable cinctipes resides in the upper to mid intertidal zone and is expected to with large fins that aid in unsteady swimming. Here, we quantified behaviorally respond to rising temperatures by shifting itsthe relationship between morphology and swimming performance distribution to a lower position in the intertidal zone. If they move across closely related species of wild-caught elephant-nose mormyrid down the shore, they will experience higher densities and likelyfishes from divergent habitats. A suite of techniques, including interact more often with a congeneric competitor, Petrolisthesgeometric morphometrics, were used to characterize differences in manimaculis. In this study, we addressed how increased density and body and...
