Etymology: Noturus: Greek, noton = back + Greek, oura = tail; refred to the position of the tail over the back (Ref. 45335); hildebrandi: Named after Samuel F. Hildebrand, a prominent American ichthyologist (Ref. 10294).
Eponymy: Dr Samuel Frederick Hildebrand (1883–1949) was born of immigrant parents who never learned to speak English and was brought up as a farm boy in Indiana. [...] (Ref. 128868), visit book page.

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Raggi anali molli: 12 - 17. Body slender; head flat. Adipose fin white or clear; pectoral fin short with 4-5 large sawlike teeth on rear edge; absence or presence of small teeth on front edge; rear edge of caudal fin straight or with slightly rounded corners; adipose and caudal fins broadly joined with tiny notch between. Color geographically variable. There are 2 subspecies: Noturus hildebrandi latus with shorter head and with 4 white or light yellow oval areas on uniform red-brown to black back; is strongly bicolored with brown to black upper side, white or yellow below. Noturus hildebrandi hildebrandi possesses longer head and prominently blotched color pattern above and almost to belly (Ref. 86798).
Adults inhabit mixed rock and sand riffles and runs of clear lowland creeks and small rivers. Often found near debris (Ref. 5723, 86798). They feed on midge and caddis larvae, together with mayfly and stonefly nymphs (Ref. 10294).
