Etymology
Hoplias australis is a species within the genus Hoplias, a word derived from the Greek hoplon, which means "shield" or "armour", an allusion to the armour created by the enlarged cranial bones and large teeth of these fishes. The specific name, australis, means "southern", a reference to this fish being one of the southernmost species in the genus Hoplias.[5]
