Short description Morfología | Morfometría

Espinas dorsales (total): 1; Radios blandos dorsales (total): 10-11; Radios blandos anales: 12 - 13. Diagnosis: body rather elongate, 6 times longer than deep; occipital process 3-5 times longer than broad (Ref. 57125). 10-11 branched dorsal-fin rays (Ref. 57125), 1st extended into long filament, following into shorter ones (Ref. 7324, 31256, 57125). Longest filament comprised 2 to 3 times in standard length (Ref. 3036, 57125). Predorsal length comprised 2.6 to 2.9 times in standard length; head width 1.6-1.9 times in head length; width of premaxillary tooth plate 2.4-2.8 times in head length; upper caudal-fin lobe often prolonged into a short filament (Ref. 7324, 57125). Upper caudal-fin lobe comprised 2.5 to 3.5 times in standard length (Ref. 57125).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00384 - 0.01800), b=2.95 (2.77 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  3.9   ±0.9 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Assuming Fec>10,000).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (48 of 100).
