Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 11; Dorsal soft rays (total): 14; Anal spines: 3; Anal soft rays: 9; Vertebrae: 24. This species is distinguished from its congeners by the following set of characters: dorsal-fin rays XI,14; pored lateral-lines scales 44-45; a series of 9-10 pores along the ventral edge of the suborbital; maxilla scaly; suborbital deeply notched above the posterior end of the maxilla; second dorsal-fin ray short, 6.5-6.8 in SL; first pelvic-fin ray filamentous; body mainly uniform olive-brown with a pale area posterior to pectoral fins; and membranes of the posterior part (between spines IX-XI) of the spinous dorsal fin black (Ref. 138836).
Body shape (shape guide): short and / or deep; Cross section: compressed.

Estimates based on models
|
Phylogenetic diversity index (Ref. 82804) |
PD50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.01862 (0.00826 - 0.04196), b=3.01 (2.81 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
3.8 ±0.6 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.). |
