Etymology: Synodontis: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ökologie
; süßwasser benthopelagisch. Tropical
Africa: Niger River, in Mopti region (Mali) and Lake Kainji (Nigeria) (Ref. 57223).
Size / Gewicht / Alter
Maturity: Lm ? range ? - ? cm
Max length : 50.0 cm SL Männchen/unbestimmt; (Ref. 31256)
Rückenflossenstacheln (insgesamt) : 1; Afterflossenstacheln: 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; post-orbital length at most 60% of snout length; maxillary barbels broadly fringed, shorter than head, unbranched and without tubercles, but with a distinct narrow membrane basal half of their anterior margins; outer mandibular barbels with few, simple and rather short ramifications; branches of inner mandibular barbels more numerous, subdivided and globose; mandibular teeth strong and rather long, numbering 17-22; pectoral-fin spines finely denticulate, the serrations being stronger on inner than on outer margin; dorsal-fin spine anteriorly smooth; humeral process deep, triangular, granulose and not keeled ventrally; adipose fin very well developed and close to rayed dorsal fin (Ref. 57223).
Coloration: after preservation, the coloration becomes entirely light beige, with numerous small, dark specks (Ref. 57223). Live specimens: entirely yellow, with a dense pattern of black specks covering body and adipose fin; other, more widely spaced specks on fins (Ref. 57223).
Maximum SL was recorded at 34.5 cm (Ref. 7362, 57223), maximum TL at 480mm (Ref. 57223). Oviparous (Ref. 205).
