Các tia vây lưng cứng (tổng cộng): 11; Các vây lưng mềm (tổng cộng): 13-14; Tia cứng vây hậu môn 3; Tia mềm vây hậu môn: 11 - 12. Body tall, with large black spot on the gill cover. Snout more than twice as long as the eye diameter (Ref. 35388).
Found in seagrass beds and sandy bottoms as well as in the surf zone commonly to depths of about 30 m, but adults may occur to 150 m depth. A sedentary fish, either solitary or in small aggregations. In spring, they often occur in brackish water coastal lagoons and estuaries. Mainly carnivorous, accessorily herbivorous (Ref. 3688). Feed on shellfish, including mussels and oysters. One of the most important fishes in saline and hypersaline aquaculture. Utilized fresh and eaten steamed, pan-fried, broiled, boiled, microwaved and baked (Ref. 9987).
Males become females at about 3 years of age (Ref. 2715, 28504). Protandric hermaphrodite species, maturing first as male (during the first or second year of age) and after the second or third year of age, as female. Spawning happens generally from October to December, with sequenced spawning during the whole period. Incubation lasts about 2 days at 16-1 7°C. Larval stages last about 50 days at 1 7.5°C or about 43
days at 20°C. Egg size 0.9-1.1 mm, larval length at hatching 2.5-3.0 mm. Simultaneous hermaphroditism is suggested for this species (Ref. 103751).
