Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 12; Dorsal soft rays (total): 18 - 20; Anal spines: 2; Anal soft rays: 20 - 22. This species is distinct with the following characters: (18-)19-20 segmented dorsal fin rays; 20-21(-22) segmented anal fin rays; 3 segmented pelvic; simple supraorbital tentacle, fusiform; head and anterior half of body with round black spots of varying sizes; upper lip and anterior head with variable black spots or stripes (Ref. 76835).

Facultative air-breathing (Ref. 126274); 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).

Estimates based on models

Preferred temperature (Ref. 123201): 24.7 - 29.3, mean 27.7 °C (based on 424 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01047 (0.00461 - 0.02381), b=2.98 (2.79 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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).
