簡短描述 檢索表 | 型態特徵 | 形態測量圖

背棘 (總數) : 14 - 16; 背的軟條 (總數) : 11 - 12; 臀棘: 3; 臀鰭軟條: 7 - 9. Diagnosis: lower pharyngeal jaw slender and gracile, with a reduced dentigerous plate; gill filaments of first arch short (ca. 10% of head length); 13-16 fleshy gill rakers on first arch; anterior gill rakers not markedly reduced in size (Ref. 81260).

生物學特性     字彙 (例如 epibenthic)

Prefers to live at depths greater than 8 m; seems to have adapted to greater depths and reduced dissolved oxygen levels; feeds mainly upon vegetative materials (higher plants and algae (Ref. 52307). Probably a pair-bonding, open (Ref. 52307) substrate brooder/spawner (Ref. 52307, 81260), with both parents guarding the brood (Ref. 52307).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
營養階層 (Ref. 69278):  2.6   ±0.1 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
