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

Africa: middle and lower Zambezi south to the Pongolo system (Ref. 7248). Absent from upper Save-Runde system (Ref. 7248). Also reported from the Luangwe (upper Congo River basin)(Ref. 58032, 82238). Reports from the Angolan Congo basin (Ref. 11970) refer to S. 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. 7248); max. published weight: 820.00 g (Ref. 7248)

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

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01072 (0.00513 - 0.02236), b=3.02 (2.83 - 3.21), 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.
