Etymology: Synodontis: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335).
Eponymy: Emmanuel-Georges Waterlot (1877–1939) was a French collector of ethnological and natural history specimens (1913–1936) in French West Africa, both for the MNHN, Paris and for the BMNH, London. [...] (Ref. 128868), visit book page.

Dimensione / Peso / Età
Maturità: Lm ? range ? - ? cm
Max length : 14.1 cm SL maschio/sesso non determinato; (Ref. 57223); peso massimo pubblicato: 85.00 g (Ref. 3799)
Spine dorsali (totale) : 1; Spine anali: 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; post-orbital length at least 60% of snout length; maxillary barbels unbranched, longer than head, without tubercles and bordered by a narrow, but rather long, basal membrane that extends over half their length; inner mandibular barbels with few, short, sometimes subdivided, ramifications; mandibular teeth moderately developed, numbering 16-27 (27 in the holotype); denticulations of pectoral-fin spines almost as strong on outer as on inner margin; dorsal-fin spine smooth anteriorly, except for some apical denticles; humeral process relatively pointed and granulose, keeled ventrally; adipose fin low, rather short, its length less than 3 times the distance between rayed dorsal- and adipose fin, pointed posteriorly and well separated from rayed dorsal fin; body entirely spotted (Ref. 57223).
Coloration: ground colour rather light with darker marblings on back and sides, less distinct on lower parts of body; all rayed fins covered with non-aligned spots; adipose fin of the same colour as body; in juveniles, spots larger, fewer and less isolated (Ref. 57223).
Body shape (shape guide): fusiform / normal.
Maximum TL was recorded at 18.5 cm (Ref. 7362, 57223). Oviparous (Ref. 205).
