Actinopterygii (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: Nichols.

Morphology | Morphometrics
soft rays: 51 - 55;
Vertebrae: 53 - 56. Diagnosis: length of vomerine tooth plate not exceeding length of premaxillary tooth plate; barbels not exceeding head length (Ref. 57129). Head rather pointed in dorsal outline; snout rounded; eyes dorsal; frontal fontanelle short and squat ('sole-shaped'); occipital fontanelle small and oval-shaped; supraorbital and `dermosphenotic' bones fused; tooth plates small; dorsal and anal fins not confluent with caudal fin; suprabranchial organ well developed; openings of secondary canals of lateral line appear as irregularly placed white spots on body (Ref. 248).
The species' biology is unknown (Ref. 78218).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00336 - 0.01560), b=2.99 (2.82 - 3.16), 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. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (17 of 100) .
