Abstract
Many amphidromous sicydiine gobies exhibit rock-climbing behavior during upstream migration along rivers and streams. Using the pelvic sucker, formed by fused pelvic fins, these gobies generate suction for adhesion on the climbing surface. By measuring performance variables that correlate to successful rock-climbing capability, we evaluated scaling relationships of suction force generated by the pelvic sucker and its fatigability during climbing in selected waterfall-climbing gobies from Japan and Hawai’i with respect to body mass. We will discuss implications of experimental results in relation to functional demands that these gobies have to meet to make a long journey upstream that requires them to overcome numerous waterfalls possible.
