Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 72 - 95; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 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): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01047 (0.00806 - 0.01360), b=2.82 (2.77 - 2.87), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 2.5 ±0.86 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Assuming tm=5-10; Fec < 1,000).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (73 of 100).

Preiskategorie (Ref. 80766): Unknown.
