Eastern Blue Groper
Achoerodus viridis
Key differences: The Eastern Blue Groper (A. viridis) is found along the eastern coast of Australia. While also exhibiting sexual dichromatism (blue males, reddish-brown females), A. viridis generally has a more slender body profile, a less pronounced nuchal hump in males, and a slightly different fin ray count. The geographic distribution is the primary distinguishing factor, with A. gouldii being western and A. viridis eastern, though their ranges can overlap in Victoria.
Humphead Wrasse
Cheilinus undulatus
Key differences: While also a large wrasse with a prominent nuchal hump, the Humphead Wrasse is found in tropical Indo-Pacific waters, not temperate Australia. It has a distinct pattern of lines on its face and a different overall body shape and fin structure.
