簡短描述 檢索表 | 型態特徵 | 形態測量圖

背的軟條 (總數) : 11; 臀棘: 4 - 5; 臀鰭軟條: 41 - 43; 脊椎骨: 37 - 40. This species is distinguished from R. molossus by having fewer branched anal-fin rays (41-43, versus 43-47). It differs from R. itupiranga by having more anal-fin rays (41-43, versus 38-41), fewer scale rows between lateral line and anal-fin origin (15-16, versus 18-19) and fewer scale rows around caudal peduncle(27-28, versus 30-31).
這種被與 R. molossus 區分藉著具有較少數分枝的臀鰭棘條.(41-43, 對 43-47) 它有別於 R. itupiranga 藉著具有更多的臀鰭棘條 (41-43, 對 38-41), 尾柄的周圍在側線與臀鰭起源 (15-16, 對 18-19) 與較少的鱗片列之間的較少的鱗片列.(27-28, 對 30-31)

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00479 (0.00182 - 0.01257), b=3.13 (2.90 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  4.1   ±0.7 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 (13 of 100).
