Jump to next section Species Information
Size 259mm or 10.2" 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 body of large specimens is uniformly brown on the sides of the body and dorsally and white ventrally. The other fins have distinct small, closely spaced, spots that do not fuse to form bands. Vague dark spots are on the sides of the body and adipose fin of juveniles. The barbels are dark. The sides and top of the head are brown and without spots. The lower side of the head is white including the lower lip. The anterior edge of the adipose fin rises steeply and reaches its maximum height at a point approximately one half the length of the adipose 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.
