簡単な記述
検索表 | 形態学 | 形態計測学
背面の脊椎 (合計) : 0; 背鰭 (合計) : 72 - 95; 肛門の骨: 0; 臀鰭: 16 - 21. Anal fin base 4.6-6.5x that of dorsal fin; 20-26 scales on caudal peduncle; body height 3.5-6.1x SL; height of caudal peduncle 1.3-3.0x of its length.
Affinities: look-alike of M. subundulatus and M. tapirus. Feeds on insects and larvae (Ref.13851). Generates electric organ discharge (EOD) of long duration that seems to correlate with territorial behavior of the species (Ref. 10460; 10601).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00792 - 0.01322), b=2.83 (2.78 - 2.88), in cm total length, based on LWR estimates for this species (Ref.
93245).
栄養段階 (Ref.
69278): 2.5 ±0.86 se; based on food items.
回復力 (Ref.
120179): 低い, ４．５年～１４年の倍増期間の最小個体群 (Assuming tm=5-10; Fec < 1,000).
Fishing Vulnerability (Ref.
59153): High to very high vulnerability (73 of 100).
Nutrients (Ref.
124155): Calcium = 187 [40, 394] mg/100g; Iron = 1.12 [0.44, 2.77] mg/100g; Protein = 18.4 [15.7, 20.6] %; Omega3 = 0.452 [0.181, 1.191] g/100g; Selenium = 96 [36, 210] μg/100g; VitaminA = 23 [8, 65] μg/100g; Zinc = 2.69 [0.60, 7.23] mg/100g (wet weight); based on
nutrient studies.
