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).

Environment: milieu / climate zone / depth range / distribution range 生態學

; 淡水 居於水底的; 河川洄游 (Ref. 51243).   熱帶; 35°N - 5°N

簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 0; 背的軟條 (總數): 5; 臀棘 0; 臀鰭軟條: 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).

生物學特性     字彙 (例如 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).

在浮游植物堆中,他們在出現之下邊緣 Eichornia 。 魚的腹部檢查後發現有浮游動物,寶刀魚與殘礫.。 (參考文獻 28714) 卵生的, 卵是沒有防衛的.(參考文獻 205)
