Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 12 - 14; Dorsal soft rays (total): 19 - 22; Anal spines: 2; Anal soft rays: 19 - 22; Vertebrae: 38 - 40. Diagnosis: Dorsal fin XII to XIV, 19 to 22, notched between spinous and segmented-ray portions; anal fin II, 19-22; pectoral rays 13-15 (usually 14); pelvic fin I, 3; caudal fin procurrent rays 10-14, segmented rays 13. Vertebrae 11-12 + 27-29. Last pleural rib on 12-13th vertebrae. Orbital cirrus simple filamentous; nasal cirri short and simple to palmate with 2-6 branches; nape without cirri. Lateral line, continuous anterodorsally below dorsal spine 6-7th to 9-10th, disconnected posteroventrally up to below dorsal spine 12-13th. Mandibular pores 4-6. Lips margin entire. Occipital crest present, higher in males (Ref. 9962). Body depth at anal-fin origin 5.6-6.1 in SL (Ref. 90102). Males with dusky bands on body, each band with a vertical pair of oblong spots; dark spot behind eye and opercle (Ref. 4404). Females with faintly dusky bands on body overlain by dark lines that break up into dashes at posterior portion; dark spots on median fins (Ref. 4404).

Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114). Common length: females usually less than 5.5 cm, males usually more than 6.0 cm in SL (Ref. 9962).

Estimates based on models

Preferred temperature (Ref. 123201): 25.9 - 29.3, mean 28.2 °C (based on 721 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00776 (0.00356 - 0.01695), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.8 ±0.3 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).
