Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 12; Dorsal soft rays (total): 13 - 14; Anal spines: 2; Anal soft rays: 15 - 16; Vertebrae: 31 - 33. Dorsal fin XII, 13 or 14, deeply notched between spinous and segmented-ray portions. Anal fin II,15 or 16. Pectoral fin 13 or 14 (rarely 14). Caudal fin 13. Vertebrae 10 + 21-23 (usually 22). Dentary incisor teeth 36-50 which includes anterior canine teeth very similar in appearance
with incisors; posterior canines usually 1 on each side. Lateral line lacking vertical pairs of pores, terminating posteriorly at point between verticals from dorsal-fin spines 10 and 12
(typically at 12). With cirrus on posterior rim of anterior nostril; absent on anterior rim.
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): 25.8 - 27.7, mean 26.7 °C (based on 175 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [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): 2.0 ±0.00 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
