Teleostei (teleosts) > Siluriformes (Catfishes) > Clariidae (Airbreathing catfishes)
Etymology: Bathyclarias: Greek, bathys = deep + Latin, clarias, -a, -um = shining (Ref. 45335).
Eponymy: Dr Edgar Barton Worthington (1905–2001) was a British zoologist with a particular interest in fisheries and waterways, and a pioneer explorer of African lakes and their fisheries. [...] (Ref. 128868), visit book page.

Issue
The species Bathyclarias gigas Jackson, 1959 is considered valid in Eschmeyer (CofF ver. Mar. 2011: Ref. 86697) following Ferraris (2007: Ref. 58032), and Seegers (2008: Ref. 78218). This is treated here as a synonym of Bathyclarias worthingtoni following Snoeks (2004: Ref. 55909).

Facultative air-breathing (Ref. 126274); Prefers rocky habitats. Feeds mainly on crabs, occasionally on fishes (Ref. 5595, 78218). Occurs down to a depth of at least 40 m, though juveniles are frequently found among rocks in very shallow water (Ref. 78218).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [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): 4.0 ±0.71 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (59 of 100).

Price category (Ref. 80766): Unknown.
