Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 8; Spine anali: 1; Raggi anali molli: 8. This species is distinguished by the following set of characters: D VI + I,7- 8, the second and third spines are the longest, with short filamentous tips reaching to between bases of first two segmented rays of second dorsal fin when adpressed; A I,8; pectoral rays 16, all are unbranched; pelvic fin I,5 with the fifth pelvic ray unbranched, 48-55% length of fourth pelvic ray; bony interorbital 53-65% pupil diameter; nape fully scaled with 12-13 scales on midline of predorsal; cheek and opercle covered with scales; scales ctenoid on breast (prepelvic); a prominent dark bar at caudal-fin base and scale pockets are strongly outlined with melanophores (Ref. 100512).

Found in caves and ledges in 107 m depth at the baseof a steep outer reef slope (Ref. 100512).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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).
