Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 19 - 23; Anal spines: 0; Anal soft rays: 23 - 28; Vertebrae: 44 - 45. Diagnosis: Marcusenius lambouri belongs to the group of species of Marcusenius with eight large circumpeduncular scales (Ref. 124516). Within this group, it can be distinguished from M. dundoensis, M. fuscus and M. sanagaensis by its low number of lateral line scales, 44-46 vs. 51-61, 54-61 and 49-56, respectively; and from M. intermedius, M. moorii and M. verheyenorum by its high number of lateral line scales, 44-46 vs. 38-43, 40-43 and 38-43, respectively (Ref. 124516). It differs from M. ghesquierei and M. kutuensis by its low number of dorsal-fin rays, 19-23 vs. 32-34 and 27-31, respectively; and from M. schilthuisiae and M. wamuinii by its lower number of anal-fin rays, 23-28 vs. 32-34 and 30-32, respectively (Ref. 124516). Finally, it differs from M. kaninginii by a high total number of vertebrae, 44-45 vs. 43-44, shallow caudal-peduncle depth, 29.6-38.2% of its length vs. 38.4-45.1%, the absence of a longitudinal black band along the flanks vs. band present, and a medial black line on each of the flank scales vs. absence of such a line on the flank scales (Ref. 124516).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01380 (0.00615 - 0.03096), b=2.86 (2.69 - 3.03), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
