Abstract
The pectoral girdle and fins of a waterfall-climbing goby, Stiphodon sp., have evolved into a pelvic sucker that allows the fish to adhere and climb on the rock surfaces of waterfalls in the oceanic islands. In this study, we constructed an artificial waterfall with a pressure transducer on the climbing surface and examined adhesive suction force and endurance during climbing in Stiphodon sp. In addition, we trained groups of the fish for endurance for several weeks and then quantified endurance-associated gene expression with biomechinal assays in order to determine if climbing-training has any effect on the pelvic muscles (protractor ischii and retractor ischii) in Stiphodon sp. We will discuss the implication of our findings.
