Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 12; Rayons mous dorsaux (Total) : 8 - 9; Épines anales: 3; Rayons mous anaux: 5. Anterior part of dorsal fin resembles a small fish, the fin also has a spot between spines 1-2 or 1-3 (Ref. 4313). Lachrymal bone with 2 spines over maxillary, first points forward, second broad, pointing out and to rear; suborbital ridge without spines except one at rear before opercle; preopercular spines short, usually only 3 developed; no supplemental preopercular spine at base of first spine; a dark spot on the spinous dorsal fin between spines 1 or 2 and 3; and vertical scale rows of about 65-75 (Ref. 10482).

Found on sand and rubble under ledges of seaward reefs (Ref. 9710). Benthic (Ref. 58302). The dorsal fin mimics a tiny fish and is used as a lure (Ref. 9710). Anterolateral glandular groove with venom gland (Ref. 57406).

Estimates based on models

Preferred temperature (Ref. 115969): 22.5 - 28.3, mean 27 (based on 299 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01259 (0.00606 - 0.02615), b=3.03 (2.86 - 3.20), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.6 ±0.4 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

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