簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 15 - 16; 背的軟條 (總數) : 10 - 11; 臀棘: 3; 臀鰭軟條: 8. Diagnosis: lower pharyngeal jaw robust, with a large, non-heart-shaped but triangular dentigerous plate, covered with stout, sparsely arrayed teeth; oral dentition coarse; outer row teeth stout bicuspids; anterior gill rakers not markedly reduced in size (Ref. 26738, 81260). Snout acute (Ref. 81260). Ventral margin of lower lip smooth; gill rakers (12-14) stout and fleshy with a crenulate median membrane connecting outer and inner row rakers (Ref. 26738, 81260). Ratio of lower jaw length to lower jaw width usually < 1 (Ref. 81260). Upper jaw with 2-4, in lower jaw with 2-3 inner tooth rows (Ref. 26738, 81260).
除了 巴可非鯽〔Tilapia bakossiorum〕 以外，有別於其他 Bermin 種, 黃非鯽〔Tilapia flava〕 與
施氏非鯽〔Tilapia snyderae〕 , 藉著結實低的咽頜具有一個三角形的有齒碟覆蓋著了矮胖的, 稀疏地佈署了齒。 能從 巴可非鯽〔Tilapia bakossiorum〕 被唇形態學區別。 (不顯著地肥大的有平滑的對下唇的邊緣,相對唇肥大的,下唇邊緣摺疊了而且邊緣了) 在口的生齒有別於 T. flava 。 (矮胖的, 厚的-頸部了二頭齒, 相對細長的, 藉由斜截形的冠) 能從 施氏非鯽〔Tilapia snyderae〕 被鰓耙形態學 (肉質的具有連接外部而內部的列耙的細齒狀的中央薄膜, 相對細長的) 區別, 而且數如果在上頜與下頜 (2-4 在上面的與 2-3 在低的, 相對 1-2 雙顎內) 的內部列齒.(參考文獻 26738)
Feeds mainly on freshwater sponges, but also filamentous algae, phytoplankton and small amounts of insects (Ref. 52307). Substrate brooder (Ref. 52307, 81260). Probably pair-bonding, with both parents guarding the brood (Ref. 52307).
