Actinopterygii (ray-finned fishes) > Siluriformes (Catfish) > Clariidae (Airbreathing catfishes)
Etymology: Bathyclarias: Greek, bathys = deep + Latin, clarias, -a, -um = shining (Ref. 45335).

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).

Africa: Endemic to Lake Malawi.

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 of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00310 - 0.01476), b=3.00 (2.82 - 3.18), based on LWR estimates for this Family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 4.0 ±0.71 se; Based on food items.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): High vulnerability (56 of 100) .

Price category (Ref. 80766): Unknown.
