|Cat-eLog Data Sheet|
|Scientific Name||Auchenoglanis wittei Giltay, 1930|
|Type Locality||Stanleyville(now Kisangani)|
|Etymology||Auchenoglanis: From the Greek, auchenos, meaning neck and glanis, meaning catfish; in reference to the long cranial shield.|
|Size||800mm or 31.5" SL. Find near, nearer or same sized spp.|
|Identification||The genus is diagnosed on the basis of a unique combination of characters: a deep and broad skull, narrow mouth, reduced pramaxillary tooth patches, anterior nostrils on the upper lip, and three large nuchal plates, the first which is in close proximity to the rear of the supraoccipital- a bone on the dorsal side of the great foramen(opening) of the skull.
The adult body is dark dorsally and laterally but light ventrally. The body has a regular pattern of dark spots in a reticulated pattern that may become vague dorsally. In some adults, two or three very dark spots are present in a line just above the lateral line. The dark spots are present in the dorsal, caudal, and adipose fins. They are less visible in the anal fin and paired fins that are otherwise brown. On small individuals, the reticulate pattern is more apparent with the spots in the dorsal and caudal fins coalescing to form bands and spots evident on all of the fins. The barbels are mostly black although the base of the external and internal mandibular barbels may be less pigmented. The upper lip is dark, lower lip is lightly pigmented. The sides and top of the head are brown and without spots. The lower side of the head is white. The anterior edge of the adipose fin rises gradually to its maximum height at the posterior end of the fin, well behind the mid-point of the fin.
|General Remarks||There is a good chance the size potential of the different species of Auchenoglanis may be much bigger than what is shown on the data pages. Some of the current data comes from studies which do not always use fully grown adult fish, sizes will be adjusted as proof of larger adult sizes are revealed.|
