Etymology: Mormyrops: Greek, mormyros = a fish (Sparus sp) + Greek, ops = appearance (Ref. 45335). More on author: Günther.
Genus incertain, in Oxymorus in ECoF. Nomenclatural issues with Mormyrops, Marcusenius and Oxyryinchus must be addressed.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (24 of 100) .
