Short description Morphology | Morphometrics

Dorsal spines (total): 1 - 2; Dorsal soft rays (total): 6-7; Anal spines: 0; Anal soft rays: 7 - 10; Vertebrae: 34 - 39. Diagnosis: dwarf species; palate edentate (Ref. 57128). Body very elongate, more than (7.5) 8 times longer than deep (Ref. 57128, 86935). 3 pairs of barbels, the maxillary pair attached to head by a broad membrane that extends over half their length (Ref. 57128). Eye more than 1/6th of head length (Ref. 86935). Humeral process short (Ref. 86935), without denticulations (Ref. 51287), less than 20% of the lateral head length (Ref. 86935). Only 2-3 barbs on pectoral-fin spines (Ref. 86935). Dorsal fin positioned shortly behind head, with 1 short spine and 6 branched rays; adipose fin long and low; anal fin with 7-9 rays and inserted below adipose fin; caudal fin forked, its lower lobe longer than upper (Ref. 57128). Coloration: preserved specimens: yellow brown; dorsal and lateral surfaces of head peppered with small melanophores; 5 dark patches along dorsal surface at nape, base of dorsal fin, between dorsal and adipose fins, at origin of adipose, below middle of adipose, on caudal peduncle; 5 dark patches mid-laterally: below base of dorsal, above vent, above origin of anal fin, below end of adipose fin, at base of caudal; a dark spot ventro-laterally on each side behind vent; dorsal fin with a faint dark bar at a level just beyond the tip of the spine; caudal fin clear basally but with a broad dark crescentic marking about the central third of fin (Ref. 86935). No broad black collar just behind the head (Ref. 51287).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±0.4 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 (16 of 100) .
