|Cat-eLog Data Sheet|
|Scientific Name||Auchenoglanis acuticeps Pappenheim, 1914|
|Type Locality||Lake Albert|
|Etymology||Auchenoglanis: From the Greek, auchenos, meaning neck and glanis, meaning catfish; in reference to the long cranial shield.|
|Size||496mm or 19.5" 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 upper body has a regular pattern of dark spots that may become vague dorsally. In small individuals the spots are large relative to those in large individuals. The spots may also be vague in the rayed and adipose fins and not at all apparent on the paired and anal fins that are otherwise brown or black. The caudal fin may be dark or with spots smaller than those on the body. On small individuals, the dark spots on the dorsal and caudal fins coalesce to form bands. The maxillary barbel is black, and the other barbels are white at the apex but may have some grey pigment distally. The upper lip is dark, lower lip is lightly pigmented. The sides and top of the head are dark and without spots. The lower side of the head is white with flecks of dark pigmentation. 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.|
