Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 15 - 17; Dorsal soft rays (total): 7 - 9; Anal spines: 3; Anal soft rays: 5 - 7; Vertebrae: 26 - 27. This species is distinguished by the following set of characters: A 5-7 (mode 6); pectoral-fin rays 12-14 (13); lateral-line pores 15-20 (18) ;total gill rakers 9-14 (10) no papillae on the upper and lower lips; prsence of supraocular spine, a small lateral lacrimal spine (sometimes absent in specimens larger than 8.78 cm SL) and suborbital spine (sometimes absent in specimens larger than 9.38 cm SL); second dorsal-fin spine length 26.5-42.8% (mean 33.9%) of SL; third dorsal-fin spine shorter or subequal to second spine, its length 74.8-97.9% (83.8%) of D2L; membrane of spinous portion of dorsal fin incised. Colouration: body with 11-15 longitudinal pale brown to dark brown bars along lateral line from behind opercular margin to caudal-fin base; irregular pale brown to dark brown blotches 1 or 2 on dorsal-fin membrane between fifth to ninth spines (Ref. 125849).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.3 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.
