    Abstract

    This study investigated the morphology of the lateral line system of the western rainbowfish (Melanotaenia australis), collected from eight habitats of the Pilbra region, Western Australia. Using fluorescence labelling, the superficial neuromast (SN) system was mapped and found to vary significantly across populations, with the SNs decreasing with increased rates of water flow under field conditions. Additionally, chemical ablation was used to determine if differences in the SN arrangement affected the fish's ability to correctly orientate at differing flow speeds. The findings suggest that the lateral line is required for orientation and is particularly important in slow water environments.
