Etymology: Mesonauta: Name not explained by Günther; probably from the Greek 'mesos' meaning middle or average, and 'nautes' for sailo (alternatively from Latin 'nauta' or sailor; the name perhaps refers to he position of dorsal fin origin posterior to the pelvic fin which was the author's principal diagnostic character.; mirificus: Named from a Latin adjective 'mirificus' meaning wonderful (Ref. 86444).

Short description Bestämningsnycklar | Morfologi | Morfometri

This species is distinguished from its congeners by its colour pattern: bar 6 including a light vertical stripe that usually divides the bar into two narrow parallel stripes below the middle of the side, and narrow dark horizontal lines along the side. It is similar to M. egregius in having bar six doubled, but with 8 or 9 (vs. 6 or 7) anal fin spines (Ref. 86444).

In blackwater rivers, among plants (Ref. 40602).

Bayesian length-weight: a=0.02692 (0.01216 - 0.05956), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.3 ±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 (10 of 100).
