Short description Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 14-15; Anal spines: 3; Anal soft rays: 8. Distinguished by the following characteristics: body depth contained 2.9-3.5 times in SL; head length 2.3-2.6 times in SL; slightly convex interorbital area; straight dorsal head profile; rounded or subangular preopercle, slightly enlarged serrae at angle; almost straight upper edge of operculum; posterior and anterior nostrils subequal in size; maxilla reaches to or beyond vertical at rear edge of eye; 2-6 rows of teeth on midlateral part of lower jaw (Ref. 89707).

Biology     Glossary (e.g. epibenthic)

Mainly found in deep reef channels and seamounts, in current prone areas (Ref. 48635). Juveniles may be found in tide pools (Ref. 5222). Feeds on reef fishes, skates, crabs, and spiny lobsters (Ref. 5222). Considered to be exceedingly territorial and very aggressive towards intruders. Vulnerable to spear fishers (Ref. 5222). Hand fed by divers in certain areas, but potentially dangerous to the inexperienced. In the Hong Kong live fish markets (Ref. 27253). Solitary (Ref 90102).

Estimates based on models

Preferred temperature (Ref. 123201): 16.8 - 27.7, mean 23.9 °C (based on 619 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00762 - 0.02872), b=3.05 (2.89 - 3.21), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.2   ±0.68 se; based on food items.
Generation time: 8.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
