Taxonomic Remarks
The species Auchenoglanis acuticeps Pappenheim, 1914 and Auchenoglanis occidentalis tchadensis Pellegrin, 1909 are considered valid in Eschmeyer (CofF ver. Jul. 2011: Ref. 87661). We postpone this change until a more complete assessment is published.

簡短描述 檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 2; 背的軟條 (總數) : 7 - 8; 臀棘: 3 - 4; 臀鰭軟條: 6 - 8. Diagnosis: head width usually less than 2/3 of standard length (Ref. 57126). Snout long and pointed, generally greater than half the head length in adults (Ref. 28714), length more than 0.9 times the head width in adults (less in juveniles) (Ref. 57126). Hind margin of adipose fin rounded; premaxillary dentition forming (in adults) two close-set oval plates (Ref. 57126). Maxillary barbel often blackish and only rarely reaching to anterior margin of opercula (Ref. 57126), usually not reaching beyond eye and much shorter than outer mandibular barbel (Ref. 28714, 81642). 8-12 (usually 10 or 11) gill rakers on lower limb of first gill arch; palatine membrane with multiple invaginations, 1-4 of them forming longer lobes; dorsal margin of cleithral process ending in a point (visible only in adults)(Ref. 57126).
Body shape (shape guide): fusiform / normal; Cross section: circular.
頭部大的很重地具有建造身體.(參考文獻 4967) 有大理石花紋，否則有斑點的灰色,具有一些排列成列的黑色斑點。

Inhabits lakes and large rivers (Ref. 4967). Has never been observed in large quantities in forested areas (Ref. 57126). Occurs in shallow water with muddy bottom. Bottom feeder, omnivore, feeds on plankton, seeds, detritus (Ref. 13868), mollusks (Ref. 13868, 28714), mud, debris (Ref. 28714), insect larvae (Ref. 6868, 28714), worms and small Crustacea (Ref. 6868). Oviparous (Ref. 205). Nested eggs are guarded by the male parent (Ref. 47642). Furthermore, the male plays host to eggs and young of Dinotopterus cunningtoni which takes advantage of the already prepared nest and feed on the host brood (Ref. 49546). An example of interspecific brood care.
棲息於湖與大河。 (參考文獻 4967) 用泥底部出現於淺水區。 雜食動物, 吃浮游生物，軟體動物，種子與碎屑。 (參考文獻 13868) 卵生的.(參考文獻 205) 被築巢的卵被由雄魚父母保衛。 (參考文獻 47642) 此外，雄魚擔任的寄主卵與利用已經準備的巢的 脂鰭鬍鯰〔Dinotopterus cunningtoni〕 的幼魚並且吃寄主窩.(參考文獻 49546) 一個種間窩照料的例子。
