The yellowedge grouper is a deep water fish (2), with an individual once reported at a depth of 390 meters (5). However, it is more commonly found between depths of 125 and 300 metres, while juveniles show a preference for shallower waters of 35 to 125 metres (4) (5).
Although most grouper species prefer reef and rocky habitats, the yellowedge grouper is found in a variety of habitats (4) (6), including areas with a sand or mud bottom. In areas with soft bottoms this species is often seen in or near trenches or burrow-like excavations (1). These burrows are usually in one of three forms: vertical, crater or trench (7). The vertical and crater burrows are thought to be precursors to the trench burrow, which can be seven or eight metres long, and up to three metres wide (6).
