Actinopteri (ray-finned fishes) > Eupercaria/misc
(Various families in series Eupercaria) > Sparidae
Etymology: Argyrops: Greek, argyros = silver, silvered + Gree, ops = appearance (Ref. 45335).
More on author: Forsskål.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 1 - 450 m (Ref. 100719), usually 5 - 100 m (Ref. 30573). Tropical; 34°N - 28°S
Indian Ocean: including the Red Sea and Persian Gulf, to Singapore and southernmost end of the Malay Peninsula.
Length at first maturity / Size / Weight / Age
Maturity: Lm 30.9  range ? - ? cm
Max length : 80.0 cm TL male/unsexed; (Ref. 124569); common length : 30.0 cm TL male/unsexed; (Ref. 3507)
(total): 11 - 13;
soft rays: 7 - 8;
Vertebrae: 24. This species is distinguished from all its congeners by the following set of characters: body deep and becoming compressed and less deep with growth; D XII,10, the first 2 dorsal-fin spines rudimentary (2 dorsal-fin spines on first dorsal pterygiophore); the dorsal-fin with two morpho types of configuration (Type I 'rigid type', fragile] as a rigid tapering spine and Type II ['flexible type', comparatively robust] as a flexible tapering spine in Group A - Red Sea, Group B - Gulf of Aden and eastern coast of Africa, and Group C - Persian Gulf, only Type II, is seen in both Group D - Madagascar to Sri Lanka and Group E - Eastern Indian Ocean, each Group is allopatric and is likely to have similar genetic structure (not analyzed in Group D or E). Colouration: body uniform pink with belly and lower jaw silvery, head red; spinous dorsal fin pink or red, other fins pink or pale pink; with pink tinge around eye; upper jaw often pinkish; anterior and posterior margins of the upper cheek scales nearly parallel just below rear edge of eye; orbit diameter is clearly less than suborbital depth (Ref. 124569).
Found in a wide range of bottoms. Young fish occur in very shallow waters of sheltered bays; larger individuals in deeper water. Feed on benthic invertebrates, mainly mollusks (Ref. 5213). Important food fish.
