Information

Description:

Dorsal spines: 11; Dorsal rays: 14-15; Anal spines: 3; Anal rays: 8.

Medium to large, moderately full-bodied grouper. Posterior nostrils larger than anterior. Maxilla reaches about to vertical at rear edge of eye. Midlateral part of lower jaw 
with 2 rows of teeth. Dorsal fin interspinous membranes deeply incised. Caudal fin convex.
  
Colour. Small juveniles pale yellowish grey, with oval black blotch on body between bases of third to ninth dorsal-fin spines. A semicircular pale band passes ventrally 
around the oval black blotch and isolates it from a dark brown band that begins broadly on nape and bifurcates just behind operculum, the upper branch curving dorsally and 
expanding broadly over basal half of dorsal fin. The lower branch also curves dorsally and expanding at base of the last 4 dorsal-fin rays. A second curved brown band, 
parallel to the one above, runs from interorbital area and rear edge of eye to a black saddle spot on caudal peduncle. A third dark brown band runs from lower edge of eye 
to subopercle and continues as a series of dark dots along ventral part of body to base of caudal fin. Fins pale yellow, except where dark markings occur on dorsal fin. As 
the fish grows this marking break up into spots and progressively fade. 
In adults most of the dark spots on body are faint or have disappeared and the dark bands on head are fading. At this stage the fins are yellowish brown, the triangular 
interspinous dorsal-fin margins abruptly orange-yellow or brownish yellow. Soft dorsal, anal, and caudal fins shading to blackish distally with a bluish white edge.


Size:

Maturity: Lm unknown. Range unknown. Max Length: 65 cm TL. 
 


Habitat and Ecology:

Inhabits relatively deep reefs and water (depth 45-375 m). Feeds on fishes and crustaceans.
 


Fishery Status:

This species is not protected or subject to fishery regulations. It is caught in the hand line fishery typically from deep water at the edge of the Mahe Plateau. It is a 
periodic but not abundant component of the catch. 


Notes:

This species belongs to the Epinephelus morrhua species complex and these species have often been confused. The specimens examined to date however have reflected the colour 
pattern of E. poecilonotus – pers obs (2019).
