The yellowedge grouper is a carnivorous species (8), feeding mainly on crabs and other invertebrates, as well as some fish (3).
A solitary species (1), the yellowedge grouper is a protogynous hermaphrodite, beginning life as a female and becoming male as it increases in age and size (4). It is thought that around half of all females transform into males by the time they reach 81 centimetres in length (1).
Sexual reproduction appears to peak between May and September (2), and the larvae of the yellowedge grouper are indistinguishable from those of the snowy grouper (Epinephelus niveatus), meaning that little is known about the very beginning of its lifecycle (4). It has recently been discovered that the yellowedge grouper may possibly have a lifespan of up to 80 years (5).
