Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 7; Rückenflossenweichstrahlen (insgesamt) : 12 - 13; Afterflossenstacheln: 1; Afterflossenweichstrahlen: 11 - 12; Wirbelzahl: 27. This species is characterized by the following: second dorsal-fin rays I, 12-13 (usually I, 12); A I, 11-12 (usually I, 11); vertebrae 10 + 17; indented tongue; posterior naris with well-developed flap on anterior rim; upper sides of the body with 12 large, closely spaced spots, these usually do not extend to dorsal edge of body; predorsal area broadly scaled to about vertical through posterior edge of preopercle (Ref. 59014).

A benthic, inshore species found in coral reefs (Ref. 75154). Also found in sand patches among reefs and rubble, often in surge areas (Ref 90102).

Estimates based on models

Preferred temperature (Ref. 123201): 23.5 - 29.3, mean 28.2 °C (based on 1855 cells).

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

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

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