Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 8; Anal soft rays: 8 - 10; Vertebrae: 31 - 32. Can be diagnosed by the following combination of characters: the female urogenital papilla
curved to the right, located laterally; border of the anal aperture in contact with the first anal-fin ray or very close to it; absence of the right hook and presence of the left one; gonopodial appendix asymmetrical, its halves different from each other, right half wider than left one; rounded tip of the hook on left half of gonopodial appendix; hook on left appendix very small; absence of a caudal peduncle spot; presence of a wide and square-shaped lateral spot in large specimens; lateral spot in adult females elliptical to roundish, but never forming a vertical bar; lateral spot always present and evident not covering more than the length corresponding to two scales length in horizontal or vertical directions (Ref. 76852).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00354 - 0.01865), b=3.16 (2.97 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
