簡短描述 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: 7 - 8. Diagnosis: lower pharyngeal jaw robust, with a large, heart-shaped dentigerous plate, covered with numerous fine, regularly arrayed teeth; mouth squared and obtuse (Ref. 81260). Lips broad and fleshy; ventral margin of lower lip folded and fringed (Ref. 26738, 81260). Fine buccal dentition of slender, movably implanted, spatulate teeth, 25-45 in outer premaxillary row (Ref. 26738).
除了 T. bakossiorum 以外,有別於其他 Bermin 種, 藉著增大唇具有摺疊與下唇的有穗邊下緣。 與在細口生齒的 T. bakossiorum 區分了細長的, 可移動地深植, 在外部的上頜骨前的列 (vs.10-15 矮胖的雙尖齒在 T. bakossiorum 中的外部上頜骨前的列中) 中的竹片狀的齒 , 25-45.(參考文獻 26738)

生物學特性     字彙 (例如 epibenthic)

Smaller specimens primarily found between sunken pieces of trees near lake shore, while larger specimens are found at greater depth - between 3 and 8 m; feeds mainly on plants and small quantities of diatoms and insects (Ref. 52307). Pair-bonding, open (Ref. 52307) substrate brooder/spawner (Ref. 52307, 81260). Biparental species that constructs a nest at a depth between 1 and 5 m, usually on a muddy bottom; pit relatively large and normally surrounded by some smaller satellite pits; when threatened, females will often seek refuge in these pits while males tend to swim away to open water (Ref. 52307). Maximum size recorded is 8.7 cm TL (Ref. 5163).
