|Cat-eLog Data Sheet|
|Scientific Name||Auchenoglanis sacchii (Vinciguerra, 1898)|
|Type Locality||Ethiopia, Southern Nations Nationalitiesand Peoples Region. Oma River at Murzu|
|Etymology||Auchenoglanis: From the Greek, auchenos, meaning neck and glanis, meaning catfish; in reference to the long cranial shield.|
|Size||308mm or 12.1" 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 original description gives only a vague one sentence description that the body is brown with darker spots on the body and fins. The diagnostic character that clearly distinguishes A. saachi from the other species is the position of the origin of the adipose fin relative to the origin of the anal fin. The holotype is in poor condition and perhaps the position of the adipose has been distorted and changed from its original position. However, the original description states that the adipose-fin origin is over the origin of the anal fin. Also Vinciquerra(1898) noted that distance between the dorsal fin and adipose fin is three times the length of the base of the adipose fin. In the other species, the length of adipose fin is much greater than the space between the dorsal fin and adipose 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.|
|Distribution||Known only from the Omo River, Ethiopia.
