Identification
The Teraglin is silvery with a brownish to bluish back. Inside the mouth and under the gill cover are both yellow. The species looks similar to the Mulloway. The caudal fin of adults is concave and the anal fin is positioned more posteriorly than that of the Mulloway. The two species have very different gas bladders.
