简单描述 型态特徵 | 形态测量图

背棘 (总数): 15 - 17; 背的软条 (总数): 9-12; 臀棘 3; 臀鳍软条: 8 - 9. Diagnosis: 3 distinct spots on flank (Ref. 47113, 57549). Supra-pectoral spot about 1.5 times supra-anal spot and in contact with the upper lateral line; supra-anal spot separate from upper lateral line; no narrow black submarginal band in dorsal fin (Ref. 57549). Male breeding coloration: black ventral body and blue to white blaze on dorsum above lateral line (Ref. 47113, 57549), until posterior end of dorsal fin and continuing onto upper margin of caudal fin (Ref. 57549). 15-18 gill-rakers; 27 dorsal rays in total; caudal peduncle length 5.9 times in SL; caudal peduncle depth 8.1 times in SL (Ref. 47113). Female C. trewavasae cannot be reliably distinguished from those of C. verduyni (ref. 57549).

生物学特性     字汇 (例如 epibenthic)

Inhabits the sand/rock interface (Ref. 47113, 57549) where sand and rocks are found in almost equal proportions (Ref. 47113). Territorial males construct a bower next to a rock, under which spawning takes place; females normally occur in small groups rarely numbering more than 10 individuals and remain close to the bottom (Ref. 57549). Mouthbrooding females remain closer to the bottom than foraging females and sometimes form small groups (Ref. 47113). Both males and females feed on plankton in the water column near the bottom and on benthic invertebrates (Ref. 57549).

Copadichromis trewavasae 出现于沙子与岩石被发现于几乎相等的比例的马拉维湖的中间栖息地中。 (参考文献 47113) 嘴繁殖期的雌性超过觅食保持更靠近底部雌性而且有时形成小群鱼群。 (参考文献 47113)

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 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.4   ±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).
