Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 1; Dorsal soft rays (total): 6; Anal soft rays: 16 - 18. Body extremely elongate, predorsal distance 26-28% of SL; and dorsal spine thin, weakly ossified and prolonged well beyond tip of first ray as long flexible filament (Ref. 56896).
Body shape (shape guide): elongated.
Appears restricted to the deep, rather swift channels of very large whitewater rivers (Ref. 56896).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00528 - 0.02384), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.8 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (25 of 100).
