Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 0; Mjukstrålar i ryggfenan (totalt): 21-25; Taggstrålar i analfenan 0; Mjukstrålar i analfenan: 26 - 32. Diagnosis: Marcusenius desertus can be distinguished from its congeners by a combination of the following characters: short snout length, 40.8-45.8% of head length; small eye diameter, 11.9-19.5% of head length; nares separation 12.7-17.6 times in head length; short preanal distance, 59.2-62.7% of standard length; short head length, 17.6-20.8% of standard length; and long anal fin, 23.7-27.4% of standard length (Ref. 113652).

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=0.00562 (0.00251 - 0.01261), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
Resiliens (Ref. 120179):  Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (15 of 100).
