Classification / Names Common names | Synonyms | Catalog of Fishes (gen., sp.) | ITIS | CoL | WoRMS | Cloffa

Actinopterygii (ray-finned fishes) > Siluriformes (Catfish) > Claroteidae (Claroteid catfishes) > Auchenoglanidinae
Etymology: Auchenoglanis: Greek, auchen = neck + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335).

Issue
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.

Africa: present in most rivers of West Africa, Lake Chad, the entire Congo River system, the Nile, East African lakes, and the rivers Omo and Giuba.

Biology     Glossary (e.g. epibenthic)

Inhabit lakes and large rivers (Ref. 4967). Occur in shallow water with muddy bottom. Omnivore, feed on plankton, mollusks, seeds and detritus (Ref. 13868). 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.
