Etymology: Synodontis: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335); vanderwaali: Named after the collector of the holotype, Ben van der Waal, in recognition of his donations of fish collections from northern Namibina rivers to the J.L.B. Smith Institute and the Albany Museum (Ref. 26674).
Eponymy: Dr Ben C W Van der Waal was a biologist at the University of Venda for Science and Technology, Thohoyandou, South Africa, which he joined (1986) and was appointed professor (1990). [...] (Ref. 128868), visit book page.

Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 1; Rayons mous dorsaux (Total) : 6; Vertèbres: 38 - 39. Diagnosed by having numerous mandibular teeth (25-41); a large number of tertiary premaxillary teeth in several rows across the width of the tooth pad; and a relatively long barbels, the maxillaries without any papillae on the leading edge. Pigment pattern with variable spots which are often drawn out to form a finely vermiculated network (Ref. 26674)

Oviparous (Ref. 205).

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=0.01514 (0.00732 - 0.03130), b=2.88 (2.71 - 3.05), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 2.9 ±0.4 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
