Teleostei (teleosts) > Siluriformes (Catfishes) > Clariidae (Airbreathing catfishes)
Etymology: Channallabes: Greek, channe, -es = an anchovy + Greek, allabes, -etos = a fish of the Nile, a kind of lamprey (Ref. 45335); teugelsi: Named after the late Guy Teugels, as a tribute to his carreer and his efforts on African catfish taxonomy, especially Clariidae (Ref. 58516).
Eponymy: Dr Guy G Teugels (1954–2003) was a Belgian ichthyologist. [...] (Ref. 128868), visit book page.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00759 (0.00343 - 0.01679), b=2.96 (2.78 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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