Dr A. Fukui (School of Marine Science and Technology, Tokai University, Japan) identified the fish as a species of Chascanopsetta, one of the Pelican Flounders. It is one of the two species know from Hawaii, either C. crumeralis or C. prorigera.

One species of Chascanopsetta is recorded from Australian waters. The Pelican Flounder, C. lugubris, occurs from off the central coast of Western Australia, around the tropical north of the country and south to the central coast of New South Wales. It grows to about 38 cm in length.
