Depth range

  • Up to 25 m



The specimen from Lizard Island photographed here is a new record for the area.

Sakai and Nakabo (2004) separated two new species that had previously been included in Kyphosus bigibbus. One of those (Kyphosus pacificus) was found by Knudsen and Clements (2013) to be a synonym of Kyphosus sectatrix. Both Kyphosus bigibbus and Kyphosus sectatrix occur in the Lizard Island area.

Identification books published prior to the revisions cited above necessarily use the old names. Prof. Kendall Clements has provided the following information:

* The photos labelled Kyphosus bigibbus on p 132 of Allen et al (2003) are of Kyphosus sectatrix.

* The photos labelled Kyphosus sydneyanus on pp 304 and 306 of Randall (2005) are both Kyphosus bigibbus. The photo of Kyphosus bigibbus on p 305 is correctly labelled (it's a young individual).

Local abundance

  • Lizard Island area: Apparently uncommon because it was first recorded from the area in Dec 2016. However, this may be due to misidentifications in the past.
