Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 10; Mjukstrålar i ryggfenan (totalt): 13-14; Taggstrålar i analfenan 3; Mjukstrålar i analfenan: 8. Distinguished by the following characteristics: adults dark brown without distinct markings; juveniles dark brown with several white spots and occasionally paler caudal fin; depth of body contained 2.3 times in SL; head length 2.2-2.3 times in SL; convex interorbital area; angular preopercle, enlarged serrae at angle and with or without few small serrae on lower edge; smooth interopercle and subopercle; posterior nostrils larger than anterior nostrils and shaped like an inverted tear drop; maxilla reaches vertical at rear edge of eye (Ref. 89707).

Biologi     Ordlista (t.ex. epibenthic)

One juvenile examined came from a depth of 55 m. Reef-associated inhabiting depths of at least 55 m (Ref. 89707). Apparently too rare to be of commercial interest.

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01349 (0.00604 - 0.03012), b=3.04 (2.87 - 3.21), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  4.0   ±0.7 se; Based on size and trophs of closest relatives
Resiliens (Ref. 120179):  Mycket låg, lägsta populationsfördubblingstid mer än 14 år (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  High to very high vulnerability (72 of 100) .
