Morphology | Morphometrics
soft rays: 38;
Vertebrae: 67. Two terminal bulbs separated by a long interspace, 1.3-2.5 times the length of distal bulb. Barbel length 43-50% SL. Four long filaments, arising together from distal end of distal bulb or from a short stem; all with numerous conspicuous bulblets of variable size. Distal bulb 0.9-1.6 times length of proximal-bulb. Axis of stem lightly, often sporadically pigmented; axis between bulbs and in filament lightly or unpigmented. Suggestion of spot at base of distal bulb in one specimen. External chevron-shaped or roundish striated areas unpigmented. Middorsal paired spots between occiput and dorsal-fin origin 8, sometimes 7 (Ref. 11333).

Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 24.8 - 25.7, mean 25.3 (based on 2 cells).
Phylogenetic diversity index (Ref. 82805
= 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), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.3 ±0.8 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (26 of 100) .
