Actinopterygii (ray-finned fishes) > Osteoglossiformes
(Bony tongues) > Mormyridae
Etymology: Stomatorhinus: Greek, stoma = mouth + Greek, rhinos = nose (Ref. 45335). More on author: Boulenger.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical
Africa: lower Congo (Ref. 1877), middle Congo River (Ref. 1877, 1878, 41590), Lake Mai-Ndombe and Wagenia Falls (Ref. 42480) in Democratic Republic of the Congo. Report from the Lomami (Ref. 41590) unconfirmed in Ref. 106245, possibly originating from the village of Lomami in Ruki drainage (Ref. 12818). Also known from 2 specimens from the Niari River in Republic of Congo; further study may reveal these specimens to belong to a new species (Ref. 81635).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5001 [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
): 3.1 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (11 of 100) .
