Etymology: Synodontis: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335); acanthoperca: The specific name is a Latinized combination of the Greek 'acantha', meaning a thorn, and the Latin 'opercul', meaning a cover or lid, alluding to the distinctive opercular spines developed by mature males in this species (Ref. 56332)
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; depth range - m (Ref. ), usually - m (Ref. ). Tropical; 0°C -
Africa: endemic to the upper Ogowe River in Gabon (Ref. 56332, 81251).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01349 (0.00601 - 0.03026), b=2.95 (2.77 - 3.13), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±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
): Low vulnerability (10 of 100) .
