Short description Morfologia | Morfometria

Spine dorsali (totale): 0; Raggi dorsali molli (totale): 21-25; Spine anali 0; Raggi anali molli: 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).

Biologia     Glossario (es. epibenthic)

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (25 of 100) .
