Actinopteri (ray-finned fishes) > Eupercaria/misc
(Various families in series Eupercaria) > Sparidae
Etymology: Acanthopagrus: Greek, akantha = thorn + Greek, pagros, a kind of fish (Ref. 45335); randalli: The specific name “randalli” is proposed in honor of Dr. John E. Randall who collected the holotype and who is clearly one of the greatest ichthyologists of all times (Ref. 82482).
Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic. Tropical
Indian Ocean: Known only from and apparently endemic to the Persian Gulf (Ref. 82482).

Morphology | Morphometrics
soft rays: 8. Body compressed; mouth somewhat oblique; maxillary reaching to below middle of pupil and lager than eye diameter; lower jaw included in upper jaw; teeth in jaws in 3 to 5 rows, anteriorly about 6 (or 7) curved canines in the upper jaw and 6 in the lower jaw; upper and lower molar teeth strongly developed, subequal in size except some progressively larger posteriorly and some progressively smaller anteriorly and posteriorly, in upper jaw up to 5 rows and lower jaw up to 4 rows; suborbital depth slightly shorter than dermal eye opening (clearly shorter than dermal eye opening); 5 (or 6) irregular transverse rows of scales on preoperculum; anterodorsal profile from just above eye ascending gently and curved; anteriormost margin of head scalation rounded when viewed from above, reaching to just beyond posteriormost margin of orbit and without small scales anterior to scalation margin; dorsal-fin spines strong, first slightly longer than half length of second spine, which is shorter than third spine; fourth or fifth spine longest; longest soft dorsal-fin ray shorter than longest spine in dorsal fin; first anal-fin spine short, its length much less than eye, robust, not flattened; second anal-fin spine length clearly less than head without snout; third anal-fin spine shorter than second spine, which is slightly longer than snout; first anal-fin ray subequal to second anal-fin spine and slightly longer than third spine; pectoral-fin tip nearly reaching to first anal-fin spine base vertically, its length clearly greater than head length; longest pelvic-fin ray clearly less than head; pelvic-fin spine longer than snout (Ref. 82482).
