As global temperatures gradually rise, variations in organisms' physiological development and behavioral responses will become increasingly apparent. Many published studies have suggested that memory is one of the most impressionable aspects of an organism during moments of environmental change. In moments of stress, humans, vertebrates, and invertebrates often show changes in learning and retaining memories. These changes can include shifts in movement patterns, increased caution or risk assessment, and altered reaction times to predators or nearby organisms. How a species interacts with its environment can drastically affect the trophic levels and interactions within its habitat, regardless of the species’ physical size. The purpose of this study is to investigate the relationship between instances of increased temperature and navigational decisions. We selected the blueband hermit crab (Pagurus samuelis) as our study species because of its ecological role as a scavenger and its regular exposure to temperature fluctuations in the rocky intertidal zone.
