Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 9; Anal spines: 4; Anal soft rays: 20 - 22; Vertebrae: 33. Color pattern on body reticulated, formed by dark pigmentation along the posterior portion of the scales. A horizontally elongate black stripe extends from a vertical through the last anal fin ray to tips of middle caudal fin rays. The caudal peduncle stripe is not preceded by a light area as that on M. oligolepis. The anterior humeral blotch is uniformly pigmented along its length. Lateral line incomplete (Ref. 41101).

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=0.01202 (0.00517 - 0.02796), 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): 3.3 ±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).
