Actinopteri (ray-finned fishes) > Siluriformes
(Catfish) > Clariidae
Etymology: Clarias: Greek, chlaros = lively, in reference to the ability of the fish to live for a long time out of water. More on author: Boulenger.

Morphology | Morphometrics
soft rays: 59 - 64. Head oval-shaped dorsally; snout broadly rounded; eyes laterally placed. Frontal fontanelle is long and narrow; occipital fontanelle small and oval-shaped. Supraorbital and `dermosphenotic' bones partially reduced (especially the latter) and distantly set. Pectoral spine short and straight; outer side with strong downward serrations. gill rakers short and distantly set. Suprabranchial organ greatly reduced. Openings of the secondary sensory canals display a regular pattern.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00759 (0.00337 - 0.01709), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.5 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.).
Vulnerability (Ref. 59153
): Low vulnerability (16 of 100) .
