Etymology: Gymnallabes: Greek, gymnos = hidden + Greek, allabes, -etos = a fish of the Nile, a kind of lamprey (Ref. 45335). More on author: Roberts.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical; 4°S - 6°S
Africa: lower Congo River basin, Democratic Republic of the Congo (Ref. 78218).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.7 cm SL male/unsexed; (Ref. 3820)
Probably lives chiefly in crevices between rocks. Its diet is unknown, but it is probably predominantly carnivorous (Ref. 78218).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.7500 [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 ±0.5 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 (10 of 100) .
