Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm ?, range 25 - ? cm
Max length : 45.0 cm TL オス/雌雄の選別がない; (Ref. 3397); common length : 22.0 cm TL オス/雌雄の選別がない; (Ref. 3397); 最大公表体重: 1.9 kg (Ref. 40637); 最大記録サイズ: 10 年 (Ref. 26328)
背面の脊椎 (合計): 11 - 12; 背鰭 (合計): 12-15; 肛門の骨 3; 臀鰭: 11 - 14. Body with 5 black and 4 grey vertical bands. Snout is longer than the eye diameter (Ref. 35388).
Inhabits coastal rocky reef areas (Ref. 12460) and Posidonia oceanica beds. Like other sparids, it is very active and frequents the surf zone, primarily at dawn (Ref. 13780). Feeds on shellfish and other benthic invertebrates which it picks from the sediment (Ref. 5377).
Life cycle and mating behavior
成熟 | 繁殖 | 放精 | 卵 | 生産力 | 幼生
Sexes separate or protandrous (Ref. 4781). In some areas, this species occurs as a digynic hermaphrodite, that is, males and females developing from intermediate juveniles (Ref. 52202). However, protandry with possible digyny was later confirmed (Ref. 103751). Reaches sexual maturity at 2 years, with an approximate size of 17 cm. Spawning happens from January to March. Egg size 0.8-0.9 mm; larval length at hatching 2.6 mm. Also Ref. 28504.
