Temperate Australasia, Tropical Indo-Pacific
Appearance varies considerably with age, and difficult to distinguish from a few other Epinephelus species. Characteristics that best distinguish it include the dense circular (rather than hexagonal) dark spots over the lower portion of the body and head, but not on the upper portion (except smaller individuals, which can have the fine spots all over). The dark blotch on the top of the tale base is also usually black, or at least much darker than other dark blotches along the back.
