Biologie     Glossaire (ex. epibenthic)

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).
Niveau trophique (Ref. 69278):  2.5   ±0.86 se; based on food items.
Résilience (Ref. 120179):  Faible, temps minimum de doublement de population : 4,5 à 14 années (Assuming tm=5-10; Fec < 1,000).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (73 of 100).
