Jump to next section Species Information
Size 310mm or 12.2" SL. Find near, nearer or same sized spp.
IdentificationThe 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 uniformly brown on the sides of the body and dorsally and white ventrally. Some vague mottling may be present. The mottling is more apparent in juveniles. The dorsal, adipose, and caudal fins have indistinct spots that sometimes fuse to form indistinct bands. The other fins are plain or with very faint mottling. The maxillary barbel is darkly pigmented and the mandibular barbels are white or slightly brown. 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 RemarksThere 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.
