Africa: middle and lower Zambezi south to the Pongolo system (Ref. 7248 , 52193 ). Absent from upper Save-Runde system (Ref. 7248 , 52193 ). Also reported from the Luangwe (upper Congo River basin) (Ref. 58032 , 82238 ). Reports from the Angolan Congo basin (Ref. 11970 ) refer to Synodontis macropuncatus (Ref. 75786 ).

Length at first maturity / Size / Weight / Age

Maturity: L m 15.0   range ? - ? cm
Max length : 43.0 cm SL male/unsexed; (Ref. 52193 ); max. published weight: 820.00 g (Ref. 52193 )

Short description Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 7; Anal spines : 0; Anal soft rays : 11 - 16.

Biology     Glossary (e.g. epibenthic)

The spines are said to be poisonous (Ref. 4537 ). Found in pools and slow flowing reaches of perennial and seasonal rivers; prefers riverine habitats to floodplains; shelters in holes or crevices or on the underside of logs, frequently in an upside-down position (Ref. 52193 ). Active at night, feeds on detritus and plant matter such as seeds as well as small invertebrates like insects and snails, and will scavenge readily (Ref. 52193 ). Breeds in summer during rainy periods (Ref. 7248 , 52193 ). Oviparous (Ref. 205 ).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous (Ref. 205 ). Distinct pairing during breeding (Ref. 205 ).

Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.01047 (0.00491 - 0.02235), b=2.99 (2.80 - 3.18), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  2.7   ±0.34 se; based on food items. Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.). Fishing Vulnerability (Ref. 59153 ):  Moderate vulnerability (41 of 100). Price category (Ref. 80766 ):   Unknown .
