Environment / Climate / Range Ecology

Freshwater; benthopelagic.   Tropical, preferred ?

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Africa: central Niger Basin (Ref. 57223). Reports from the Cross basin (Ref. 52861, 85170) need confirmation.

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 36.0 cm SL male/unsexed; (Ref. 57223)

Short description Morphology | Morphometrics

Dorsal spines (total): 1; Anal spines: 0. Diagnosis: (the description that follows fits the only whole specimen identified as this species, the type specimen being reduced to a skeleton) gill slits not extending ventrally beyond pectoral-fin insertions; maxillary barbels not fringed, longer than head, without branches or tubercles, but with a distinct, short, basal membrane; mandibular barbels with thick, subdivided ramifications, those of the inner pair even tuberculate; mandibular teeth moderately developed, numbering 55; denticulation on pectoral-fin spines weaker on outer than on inner margins; dorsal-fin spine anteriorly smooth; 1st ray of dorsal and anal fins, as well as both caudal-fin lobes, prolonged into filaments; humeral process pointed, granulose and with 3 backwards pointing spines on ventral margin (young individuals have only the posterior spine slightly developed); adipose fin normally developed and rather distinctly separated from rayed dorsal fin (Ref. 57223). Coloration: body of the alcohol-preserved specimen uniformly light brown (Ref. 57223).

Biology     Glossary (e.g. epibenthic)

Maximum total length was recorded at 43.0cm (Ref. 57223). Oviparous (Ref. 205).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00264 - 0.01508), 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 (Ref. 69278):  2.8   ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 439 - 1,889).
Vulnerability (Ref. 59153):  Moderate vulnerability (41 of 100) .
Price category (Ref. 80766):   Unknown.
