Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 13; Rückenflossenweichstrahlen (insgesamt) : 10 - 11; Afterflossenstacheln: 2; Afterflossenweichstrahlen: 10 - 11; Wirbelzahl: 26. This species is distinguished by the following characters: D XIII,10 or 11; A II,10 or 11; pectoral rays 17 or 18; spiniform caudal rays 3; tubed lateral-line scales 13 or 14; gill rakers 9 + 20 or 21 = 29 or 30; body depth 2.0-2.1 in SL; color overall dusky bluish grey, except dark grey on anterior half of head and bright yellow on nape and upper back above lateral-line; fins mainly translucent whitish except caudal fin lobes and basal portion of soft dorsal fin dark grey; color in alcohol mainly mottled brown with translucent whitish fins (Ref. 79629).

The type locality is a steep drop-off adjacent to a small islet that is part of the Fam Group in the Raja Ampat Islands (Indonesia). About 10 individuals were observed hovering near a ledge in 62 m depth (Ref. 79629). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01778 (0.00796 - 0.03971), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.1 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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