Electroreception is the sense that allows organisms to detect weak electrical fields in the environment to detect prey or predators, orientate themselves through the Earth’s geomagnetic field, and communicate with conspecifics. Several decades of research on the electroreceptive ampullae of Lorenzini of elasmobranchs have shown that their morphology and distribution vary among species, and this has been attributed to be a function of differences in environment and lifestyle. The estuary stingray, Dasyatis fluviorum, the blue-spotted maskray, Neotrygon kuhlii, and the brown whipray, Himantura toshi, are three dasyatids common in Moreton Bay, Queensland, Australia. Despite foraging sympatrically for benthic prey over intertidal sand flats their diets differ; N. kuhlii feeds primarily on polychaetes, D. fluviorum on brachyurans and H. toshi on caridean shrimp. We used light, confocal, scanning electron and transmission electron microscopy to assess whether morphological differences in their electrosensory system might explain their seeming ability to differentiate among buried prey. The electrosensory systems of these species were generally of similar morphology; however, previously undocumented features such as the peculiar shape of the ampullary canals and of their supportive cells in the ampulla proper were identified.
