Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 7; Radios blandos dorsales (total) : 10 - 11; Espinas anales: 1; Radios blandos anales: 11. This species is characterized by the following, D VI+I,10-11; A I,11; pectoral-fin rays 15; longitudinal scale series 27; cheek scales extending nearly to a vertical at anterior edge of orbit; median predorsal scales extending to posterior interorbital space; fully scaled prepectoral area; 2+4 gill rakers; body depth at origin of pelvic fins 3.9-4.25 in SL; very compressed body, width 1.55-1.8 in body depth; head length 3.25-3.3 in SL; first dorsal fin higher than second, with longest spine 1.25-1.5 in HL; caudal fin is longer than head, 2.7-2.8 in SL (Ref. 82658); moderately large Gnatholepis (up to 58 mm SL) with nape midline scales always cycloid and most of predorsal scales cycloid; body pale with 6-8 rows of staggered dark brown spots, mid-lateral spots may be largest; transverse black line on the upper part of the eye joining somewhat oblique to curved black line or bar crossing cheek and ending well behind end of jaw; third to fourth first dorsal fin spines longest, fin with square to rectangular appearance when extended; lateral scales 26-29, usually 27; 9-11 predorsal scales (usually 10), all cycloid (Ref. 92171).

Inhabits mud-sand bottoms with Caulerpa green alga in 1-12 m (Ref. 90102).

Estimates based on models

Preferred temperature (Ref. 123201): 23.5 - 29.3, mean 28.6 °C (based on 995 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00977 (0.00444 - 0.02153), b=3.04 (2.85 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
