簡単な記述 形態学 | 形態計測学

背面の脊椎 (合計): 3; 背鰭 (合計): 26-29; 肛門の骨 0; 臀鰭: 23 - 26. Tall, with a small mouth and plate like scales (Ref. 35388).

生物学     用語集 (例 epibenthic)

Inhabits bays, harbors, lagoons, and seaward reefs (Ref. 9710). May drift with young at surface among Sargassum (Ref. 9710). Usually solitary or in small groups (Ref. 9710). Feeds on benthic invertebrates like mollusks and crustaceans (Ref. 4727). Oviparous (Ref. 205). Consumed mostly fresh, smoked, and dried salted. The flesh is of excellent quality. Because it is resistant to capture, it proliferates and competes for food with other species (Ref. 5377).

Life cycle and mating behavior 成熟 | 繁殖 | 放精 | | 生産力 | 幼生

Adults guard the embryos nested in sand which hatched in about two days (Ref. 9778).
