Short description Morfologia | Morfometria

Raggi dorsali molli (totale): 74; Raggi anali molli: 37; Vertebre: 45. This species is distinguished from its congeners by the following characters: sooty black nasal chambers; few anal fin rays (37 vs. 49-54), few vertebrae (45 vs. 54-58), a wider head (12.0 % SL vs. 7.7-9.8 % SL); a pair of sub-dermal spines fused to form a broad ridge on frontal just behind eyes, a small, median, sub-dermal, ethmoidal spine just in front of eyes and an antero-ventrally directed spine at lower angle of preopercle (all spines covered by skin); anterior gill arch with 3 developed rakers, only slightly larger than the spiny knobs, gill filaments 7-8 times length of developed rakers; slightly prolonged pectoral peduncle; palatines with several tooth rows; vertebrae, precaudal 16 and total 45; fin rays, D 74, A 37, caudal 10 and pectoral 18 (Ref. 93007).

Rare species, known from a single specimen (Ref. 34024), apparently living on a shallow reef (Ref. 93007).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 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).
