背面の脊椎 (合計) : 6 - 7; 背鰭 (合計) : 9 - 10; 肛門の骨: 1; 臀鰭: 9. Characterized by pale grey body with five diffuse brown saddles along back; midside with 4-5 diffuse brown blotches; head and body with scattered white spots; presence of diagnostic greenish patch behind upper edge of operculum; rounded caudal fin; longitudinal scale series 25-26; scales absent on head except upper half of opercle and predorsal fully scaled; mainly ctenoid body scales; depth of body 5.3 in SL (Ref. 90102).
Body shape (shape guide): elongated; Cross section: circular.
Occur along coastlines and in estuaries and harbors. Usually found in brackish tidal waters. Feed on invertebrates. Found to contain tetrodotoxin (TTX) and anhydrotetrodotoxin (anh-TTX) which causes paralytic food poisoning (Ref. 54777). Marketed fresh in Mekong delta (Ref. 12693).
