Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 9; Rückenflossenweichstrahlen (insgesamt): 12; Afterflossenstacheln 3; Afterflossenweichstrahlen: 12; Wirbelzahl: 25. This species is characterized by the following: D IX,12, the first two dorsal spines flexible and shorter than longest dorsal soft rays; body depth 3.1-3.35 in SL; cheek scaleless; 2 small scales dorsally on opercle; gill rakers 17-20; juveniles and females whitish with a red stripe from above eye to back at base of dorsal fin; males with a pale-edged black spot on seventh lateral-line scale and scales below (Ref. 75958).

Found solitary or in small groups near reefs in sand-rubble bottoms (Ref. 90102). Feeds on small benthic invertebrates (Ref. 89972). Maximum depth reported taken from Ref. 128797.

Estimates based on models

Preferred temperature (Ref. 115969): 26.5 - 28.8, mean 27.9 (based on 72 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00397 - 0.02640), b=3.06 (2.84 - 3.28), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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