Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm SL male/unsexed; (Ref. 6205)
(total): 13 - 14;
soft rays: 22 - 24;
Vertebrae: 39 - 40. Swim bladder with two posterior extensions. Body is pale brown to dull brown above, lighter below; a faint mid-lateral stripe usually present; dorsal fins dusky terminally with five or six rows of dusky spots on second dorsal fin membranes, other fins hyaline.
Found in tidal flats in the estuary zone near large rivers. Oviparous (Ref. 205). Fishery is declining possibly due to habitat alteration by reclamation and pollution. The flesh is firm and well accepted in Japan (Ref. 6205).
