Etymology: mutum: The specific name is in reference to the Brazilian popular name of the curassow birds of the genus Crax Linnaeus, which are typically dark colored, as well as the fins of Moenkhausia mutum , and also refers to the Nova Mutum Municipality, the type locality, and where most of the type specimens were collected. A name in apposition.
Eponymy: Dr William J Moenkhaus (1871–1947) was an American geneticist and ichthyologist who became Professor of Physiology at Indiana University Medical School (1904–1941), where he was Eigenmann’s colleague. [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 10 - 11; Vertebrae: 32 - 33. Moenkhausia mutum can be differentiated from other species of Moenkhausia, except M. hemigrammoides, M. nigromarginata and Moenkhausia rubra by having intense diffuse dark pigmentation on the dorsal and anal fin-rays, especially in anteriormost rays and in the distal portion (vs. fins hyaliane or only with scattered chromatophores). It differs from M. rubra by having 20-23, modally 21 branched anal-fin rays (vs. 17-20, modally 19) and by having a vertically elongate humeral spot (vs. approximately rounded); from M. hemigrammoides by having intense dark pigmentation on pelvic fin (vs. hyaline), by the anal fin with a relative diffuse dark pigmentation (vs. presence of a black oblique line extending from the urogenital cavity to the tip of second or third branched anal-fin ray), and by the absence of a well-defined black spot on the distal portion of the dorsal fin (vs. presence); and from M. nigromarginata by lacking a series of longitudinal dark zigzag stripes on body formed by the concentration of dark chromatophores in the upper and lower portions of the exposed area of scales (vs. presence) and by having a vertically elongate roughly rectangular humeral spot surpassing the lateral line ventrally (vs. humeral spot approximately rounded, with an anteroventral projection not surpassing the lateral line ventrally) (Ref. 109750).

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=0.01230 (0.00522 - 0.02900), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.4 ±0.5 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).
