Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale zachte stralen (totaal) : 14. This species is distinguished from its congeners by the following set of characters: 28 tail rings; 14 dorsal fin rays; 9 pectoral fin rays; 4 subdorsal rings; bilaterally paired wing-like protrusions are formed by a pair of large truncate spines projecting laterad on first superior trunk ridge; elevated dorsal ridge is formed by unique triangular bony mounds dorsally on second, the third and fourth trunk rings with the posterior mound less pronounced; a large and prominent spine projecting laterad on eighth lateral trunk ridge (Ref. 118476).

This species was not associated with a particular host. It has been observed in association with mixed soft coral, Halimeda sp. (coralline algae) and hydroids on rocky reef walls and large boulders in both exposed and semi-sheltered locations (Ref. 118476)..

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [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).

Trofisch niveau (Ref. 69278): 3.0 ±0.5 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
