Etymology: Synodontis: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ecologia
; acqua dolce benthopelagico; potamodromo (Ref. 51243). Tropical; 22°C - 25°C (Ref. 2060); 10°N - 5°N
Africa: Sassandra, Boubo, Bandama, Angébi, Mé, Comoé Bia and Tano rivers in Côte d'Ivoire (Ref. 272, 57223, 83625), Burkina Faso (Ref. 57223) and Ghana (Ref. 30488).
Size / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 22.5 cm SL maschio/sesso non determinato; (Ref. 83624); peso massimo pubblicato: 197.00 g (Ref. 123661)
Spine dorsali (totale) : 1; Spine anali: 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; eye not more than 20% of head length, and 26% of head width; in adults, post-orbital length at least 60% of snout length; maxillary barbels usually longer than head (except in young individuals), unbranched, without tubercles but with a broad, black basal membrane; outer mandibular barbels with rather long, tuberculate ramifications; branches of inner mandibular barbels shorter and strongly globose; mandibular teeth long, numbering 27-38 (33 in the holotype); dorsal-fin spine smooth anteriorly; denticulations of pectoral-fin spines finer on outer than on inner margin; humeral process not keeled ventrally, triangular, slender and pointed in young specimens, and deep, more strongly arched, and more blunt posteriorly in adults; dorsal- and pectoral-fin spines prolonged into a black filament; adipose fin not very well developed; head more flattened in young than in adults; outer margins of caudal-fin lobes black-edged; body covered with fine specks (Ref. 57223).
Coloration: body rather pale and covered with fine black specks and with larger spots in young individuals; rayed fins light and often spotless, but adipose fin always spotted; outer margins of caudal-fin lobes black-edged; broad black spot above humeral process (Ref. 57223).
Maximum TL was recorded at 28.1 cm (Ref. 7362, 57223). Oviparous (Ref. 205).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00635 - 0.01728), b=2.81 (2.68 - 2.94), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.9 ±0.3 se; based on size and trophs of closest relatives
Generation time: 2.6 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (28 of 100).
