Species Epinephelus morrhua (Valenciennes, 1833)

Comet Grouper, Comet Cod, Comet Groper



Ma & Craig (2018) placed this species in the genus Mycteroperca based on genetic studies. However, no distinct morphological characters uniquely separate the two genera as recognised by that study. That separation makes identification to genus difficult. Tentatively we retain the species in Epinephelus.




New South Wales, Northern Territory, Queensland, Western Australia
