More Info


Northeast of Flinders Island, Bass Strait, Victoria, to south of Encounter Bay, South Australia, and possibly west to Spencer Gulf, at depths to 80m.


Dorsal fin 79-90; Anal fin 51-59; Pelvic fin right 12, left 5; Caudal fin 14.
Body deep (46-57% SL); head moderately small; eyes small, adjacent to each other; snout extended into a hook-like process projecting downwards in front of small, oblique mouth. 
Scales ctenoid, very small, rather firmly attached on both sides; lateral line present on both sides; almost straight, ending posteriorly on head. 
Dorsal, anal and caudal fins separate; dorsal fin arising on tip of snout, without elongate anterior rays; caudal fin rounded; right pectoral fins only slightly longer than the left; pelvic fin on eyed side (right side) with an elongate base.


A small species, reaching only 10cm TL.


The eyed side (right side) is pinkish in colour with numerous small dark grey ocelli (an eye-like spot with a pale marginal ring) on the head and body. In some cases, the Largescale Flounder is darkly speckled. The fins are dotted with dark grey. The blind side of the fish (left side) is whitish in colour.


Perhaps the smallest member of the genus. Is often confused with juveniles of similar species, such as the Spotted Flounder which are commonly found in the same areas as the Largescale Flounder. It is frequently taken by trawlers in South Australian prawn grounds.
