📖 Overview

Adults are found in streams and rivers of lowland regions, above tidal influence. Collected from generally clear waters (sometimes in turbid waters), over bottoms usually consisting of gravel, sand and some mud. They feed mostly on algae and bottom detritus. Little is known of the life history, but it probably has a marine larval stage. Only recently described, although it has long been misidentified as Awaous crassilabrus, a species that does not occur in Australia .
