Malapteruridae (Electric catfishes)
Etymology: Malapterurus: Greek, mala = a lot of + Greek, pteron = fin + Greek, oura = tail (Ref. 45335); minjiriya: "Minjiriya" is the Hausa word for the species, easily distinguished from the sympatric M. electricus by Niger River fishermen (Ref. 44050).
Environment: milieu / climate zone / depth range / distribution range

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=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (45 of 100).
