生物学特性     字汇 (例如 epibenthic)

Affinities: may be sympatric with R. senegalensis and R. steindachneri and has always been mistaken for R. senegalensis, which is the reason for it not being discovered. Maximum TL was recorded at 12.5 cm (Ref. 2801).

分类相关: 也许与 R. senegalensis R. steindachneri 重叠分布并且已经总是被误认为 R. senegalensis, 是它的理由不被发现。 最大体长TL记录为 12.5 公分。 (参考文献 2801)

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=0.00589 (0.00282 - 0.01229), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
