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).

Short description Morfología | Morfometría

Espinas dorsales (total): 1; Radios blandos dorsales (total): 7; Espinas anales 0; Radios blandos anales: 11 - 16.

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).

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).

Nivel trófico (Ref. 69278): 2.7 ±0.34 se; based on food items.

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (41 of 100).
