Actinopterigi (pesci con pinne raggiate) > Siluriformes (Catfish) > Schilbeidae (Schilbid catfishes)
Etymology: Siluranodon: Greek, silouros = a cat fish + Greek, odous = teeth (Ref. 45335);  auritus: From the Latin "auritu" (literally "listening"), referring to the local Arabian name of this species in Egypt, "schilbe oudney", which means "schilbe with ear" (those "ears" probably refer to the large rounded pectoral fins just behind the head)(Ref. 43912).

Short description Morfologia | Morfometria

Spine dorsali (totale): 0; Raggi dorsali molli (totale): 5; Spine anali 0; Raggi anali molli: 67 - 87. Diagnosis: 67-87 anal-fin rays; 49-60 thin and flexible gill rakers on lower limb of first gill arch; 4 pairs of well developed barbels; small, spineless dorsal fin with 4-5 branched rays; jaws and palatine bones entirely without teeth (Ref. 43912, 57127).

Biologia     Glossario (es. epibenthic)

Pelagic, occurs large and moderate lakes and rivers (Ref. 43912). In the Sudd, they occur beneath fringing Eichornia (Ref. 28714). Microphagous, feeding mainly on algae and occasionally rotifers, planktonic and benthic crustaceans, immature insects (Ref. 43912) and mud/debris (Ref. 28714, 43912). Probably reproduces during the floods, migrating from lakes to rivers; howver in Lake Kainji fish were reported to migrate from the river to the Lake to spawn (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205). Max. reported total length 175 mm (Ref. 3570, 43912). Might locally represent an important species for fisheries since it is sometimes extremely abundant, but this may be negated by its small size (Ref. 43912).
