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).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal spines: 3; Anal soft rays: 8; Vertebrae: 35. Diagnosis: relatively small species, with a maximum standard length below 50 mm (Ref. 56332). Distinctive color pattern including a pair of dark patches on the caudal fin, one patch in the middle of each lobe; posterior margin of opercle with a bony spine (small in females, elongate in males)(Ref. 56332, 81251). Dorsal spine only serrated along posterior edge (Ref. 81251).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01549 (0.00697 - 0.03443), b=2.90 (2.72 - 3.08), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±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.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
