生物學特性     字彙 (例如 epibenthic)

Facultative air-breathing in the genus (Ref. 126274); Occurs in rapids where it lives in the rocky anfractuosities in the strong current zones. The length of the male snout bristles might be related with the hierarchic level of the individual within the population. Fished by harpoons or bows in the shallow zones (Ref. 35381).

出現於急流在那裡它在強的海流區中生活在岩石的彎曲水道中。 雄魚吻部短鬚的長度可能被與族群裡面的個體的 hierarchic 水平有關。 在淺水區中藉著魚叉或弓捕獲。 (參考文獻 35381)

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=0.01514 (0.00712 - 0.03216), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
回復力 (Ref. 120179):  中等的, 族群倍增時間最少 1.4 - 4.4年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (14 of 100).
