Auchenoglanididae (Flatnose catfishes)
Etymology: Parauchenoglanis: Greek, para = near + Greek, auchen = neck + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335).
Eponymy: Dr Christoph Gustav Ernst Ahl (1898–1945) was an ichthyologist, herpetologist and aquarist. [...] (Ref. 128868), visit book page.

экология
; пресноводный демерсальный. Tropical; 5°N - 2°N
Africa: endemic to the upper Cross River basin in Cameroon (Ref. 81642).
Size / Вес / Возраст
половая зрелость: Lm ? range ? - ? cm
Max length : 10.5 cm SL самец/пол неопределен; (Ref. 81642)
колючие лучи спинного плавника (общее число) : 2. Diagnosis: caudal peduncle relatively long, with minimal depth as large as horizontal distance between adipose and caudal fin bases, or slightly larger (never twice as large)(Ref. 81642). Pectoral spine only partially and slightly, or not at all, serrated on its anterior margin; preorbital head length less than maximum head depth (Ref. 50834, 81642). Colour pattern on flank strongly marked in most cases; adipose fin height 3-7% SL, dorsal fin height 15-25% (28%) SL; head depth 56-88% head width (Ref. 81642). Barbels long, e.g. external mandibular barbel minimally 1.3 times HL, reaching to beyond tip of pectoral fin spine, maxillary barbel always reaching base of pectoral fin spine or even further (Ref. 50834, 81642). Whole body with equally large dots (Ref. 81642).
Body shape (shape guide): elongated.

Estimates based on models
Phylogenetic diversity index (ссылка
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00218 - 0.01265), b=3.09 (2.88 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (ссылка
69278): 3.5 ±0.5 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (ссылка
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
