Malapteruridae (Electric catfishes)
Etymology: Malapterurus: Greek, mala = a lot of + Greek, pteron = fin + Greek, oura = tail (Ref. 45335); stiassnyae: Named to honor the collector of the holotype, Melanie L. J. Stiassny (American Museum of Natural History, New York), who has raised an eloquent voice in conservation matters (Ref. 44050).

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).
Trofisk nivå (Ref.
69278): 3.4 ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (27 of 100).
