Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 10; Spine anali: 1; Raggi anali molli: 9. Diagnosis: Color generally light bluish grey in life with small yellow to brownish orange spots on the head and body, those on body mostly conjoined to form longitudinal stripes along scale rows; 4 pairs of dark brown spots on lower side of body, followed by a single spot at the caudal-fin base; a few smaller dark brown spots on body, mostly in a row dorsally and one ventrally; dorsal and caudal fins are covered with numerous, relatively large, orangish to yellowish brown spots. Pectoral rays 17; segmented caudal-fin rays 17; branched caudal-fin rays typically 13, rarely 12, 14 or 15; dorsal-fin spines elongate and filamentous, the second one the longest 1.59-2.07 in SL. Longitudinal scale series 28 (28-30).

Biologia     Glossario (es. epibenthic)

Usually found in clear water in the vicinity of coral reefs, usually on sand or rubble bottoms (Ref. 57733). Solitary (Ref. 90102).

Estimates based on models

Preferred temperature (Ref. 123201): 25.3 - 28.9, mean 27.7 °C (based on 290 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
