POLL, 1954: 62
, Fig. 17, Pl. 3, Figs. 3,7 & 8.
Diagnosis
: Dorsal fin XL, 14- 15; anal fin III,9; pectoral fin rays 18 -21; lateral-line scales 64-75; lateral scale series 104- 112; gill-rakers 7- 10 + 13- 15, including 2- 6 rudiments on each limb. Body deep, the greatest depth contained 2.4-2.8 times in SL (for fish 10-39 cm. SL); head large, the length contained 2.2-2.5 times in SL; pectoral fins length 1.4- 1.9 times in head length; pelvic fins subequal to pectorals, reaching to or beyond anus in fish of 10-30 cm. Caudal fin rounded; dorsal fin with the third or fourth spine longest, but distinctly shorter than the longest rays; interspinous membranes of dorsal fin deeply incised. Interorbital area convex; eye diameter greater than interorbital width in fish less than 30 cm. SL and distinctly less than interorbital width in a fish of 39 cm. SL. Preopercle with enlarged serrae at the angle, and 1 -6 small serrae (usually covered by skin) on ventral edge; opercular spines distinct; upper edge of operculum convex. Maxilla naked, usually not reaching past vertical at rear edge of eye; no step on ventral edge of maxilla; midlateral part of lower jaw with 2 rows of teeth, the inner teeth about twice as long as the outer ones. Rear nostrils 2 or 3 times larger than front ones. Lateral body scales ctenoid; no auxiliary scales. Pyloric caeca very numerous, forming a large dendritic mass.
Colour
: Head and body dark brown; soft dorsal, caudal and anal fins blackish distally (where there are no scales), the basal (scaly) part of these fins not so dark; soft dorsal, caudal, anal and pectoral fins usually with white edge; pelvic fins blackish; prominent black streak on cheek at upper edge of maxilla.
Maximum size, 110 cm. total length, 25 kg. (
POLL, 1954
).
GEOGRAPHICAL DISTRIBUTION
Eastern Mediterranean to southern Angola (14° S). I have examined specimens from the coasts of Israel, Togo, Nigeria, Cameroun, Congo and Angola.
REMARKS
Found on bottoms of mud, sand or rock in depths of 90-220 rn.
POLL, 1954
). In the literature on Mediterranean and west African groupers (
CADENAT, 1935
;
TORTONESE, 1970
;
BAUCHOT & PRAS, 1980
; etc.)
E
.
haifensis
may have been confused with
E
.
marginatus
under the name of "
Epinephelus guaza
" or "
Epinephelus gigas
" Although
only 19 specimens of
E
.
haifensis
have been examined, they all have 9 anal fin rays; whereas, 79 of the 80 specimens of
E
.
marginatus
that were counted have 8 anal fin rays. Consequently, references to
E
.
guaza
with 8 or 9 anal fin rays could apply to either or both species.
The species described as
Perca gigas
by
BRÜNNICH (1768)
may be the same as
E
.
haifensis
, but the pectoral fin count of 16 given by BRUNNICH is too low. and the colour description ("
corporis ochraceus
,
obscuro fuscoque
nebulosus
;
caput subtus rubrum ut & pinnae pectorales extrorsum
." [body yellowish, with indistinct dark blotches; lower part of head and margin of pectoral fins reddish]) is more similar to the colour pattern of
E
.
marginatus
. Without a type specimen,
Perca gigas
is probably best regarded as a
nomen dubium
.
The stuffed holotype of
Cerna sicana
DODERLEIN
from Sicily has only 10 dorsal fin spines.
TORTONESE (1956)
redescribed this specimen and concluded that it was not the western Atlantic species
E
.
nigritus
, which normally has 10 dorsal fin spines. Except for having only 10 dorsal fin spines, this specimen fits the description of
E
.
haifensis
given above.
Cerna sicana
may represent a rare species with 10 dorsal fin spines that is known from only a single specimen, but it seems more likely that this holotype is simply an abnormal specimen of
E
.
haifensis
. Rather than use
E
.
sicana
as the valid name for a species that normally has 11 dorsal fin spines,
Epinephelus haifensis
is here accepted as the valid name for this species.
