Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 72 - 95; Espinhos anais: 0; Raios anais moles: 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).

Nível Trófico (Ref. 69278): 2.5 ±0.86 se; based on food items.

Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Assuming tm=5-10; Fec < 1,000).

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

Categoria de preço (Ref. 80766): Unknown.
