Etymology: Parananochromis: Greek, para = the side of + Latin, nannus = small + Greek, chromis = a fish, perhaps a perch (Ref. 45335); brevirostris: From the Latin brevis, short and rostrum, beak or snout, in reference to the short, rounded snout of the species (Ref. 50579).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical
Africa: Ivindo and Ogowe drainages in Gabon (Ref. 50579, 81260, 97361). Reports from the Ntem River (Ref. 50579, 81260) are misidentifications for Parananochromis elobatus (Ref. 97361).

= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00684 - 0.03200), b=2.98 (2.81 - 3.15), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.2 ±0.4 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
