Short description Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 18-20; Anal spines: 3; Anal soft rays: 8 - 10. Distinguished by the following characteristics: body and fins black with many large white blotches (Ref. 13608). Compressed, with a large pectoral fin; scales smooth (Ref. 26938); greatest depth of body 2.2-2.5 in SL; body width 2.2-2.9 times in depth; head length 2.5-2.8 times in SL; rounded preopercle, finely serrate, serrae at the angle slightly enlarged (Ref. 089707).

Biology     Glossary (e.g. epibenthic)

Usually on deep ledges, at depths to 210 m and on reefs, usually in caves or deep crevices (Ref. 7251). Solitary (Ref. 26340) and secretive, darts away when approached or frightened (Ref. 9710). Rarely seen in markets. Major threat to this species is fishing pressure (Ref. 089707).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00465 - 0.01558), b=3.16 (2.99 - 3.33), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic Level (Ref. 69278):  4.5   ±0.80 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  High vulnerability (61 of 100) .
Price category (Ref. 80766):   Very high.
