Etymology: Argyrops: Greek, argyros = silver, silvered + Gree, ops = appearance (Ref. 45335).

Maturity: Lm ? range ? - ? cm
Max length : 50.0 cm SL オス/雌雄の選別がない; (Ref. 124569); common length : 30.0 cm SL オス/雌雄の選別がない; (Ref. 124569)
背面の脊椎 (合計) : 10 - 11; 背鰭 (合計) : 9 - 11; 肛門の骨: 3; 臀鰭: 8 - 9. This species is distinguished from all its congeners by the following set of characters: body deep and compressed; D XI,10 (rarely X,11); first dorsal-fin spine rudimentary (one dorsal-fin spine on first dorsal pterygiophore), the second to sixth spines (usually 5, rarely 4) are much elongated and flattened in juveniles 15-25 cm SL (second spine often reaching beyond level of last dorsal soft rays, shorter and reaching first soft dorsal-fin ray base in specimens of ca. 30 cm SL); orbit diameter clearly less than suborbital depth; pupil diameter greater than preorbital length in specimens less than 20 cm SL, but pupil diameter is clearly less than preorbital length (more noticeable in specimens greater than approx. 30 cm SL; the rear margin of upper jaw extends to a vertical beyond orbit diameter; body bars reddish, often present to 25 cm SL; all fins reddish hyaline (Ref. 124569).
Inhabits sandy and muddy bottoms (Ref. 41299). Important food fish. In Okinawa (Japan), according to local fishermen, this species usually reches more thatn 50 cm SL and a buyer from Ryukyu Is. reported that some individuals occasionally attain 65 cm SL (Ref. 124569).
