Dorsale stekels (totaal) : 14 - 17; Dorsale zachte stralen (totaal) : 10 - 12; Anale stekels: 0; Anale zachte stralen: 8 - 10. Diagnosis: 3 lateral spots on the body (Ref. 57549). Supra-pectoral spot about 1-1.5 times the supra-anal spot (Ref. 57549) and overlapping upper lateral line (Ref. 42940). Supra-anal spot present (Ref. 42940, 57549). Spots in the rayed portion of dorsal fin yellow; anal fin black (Ref. 42940). Breeding males with wide yellow marginal band in anal fin (Ref. 42940, 57549), blue breast and a narrow black submarginal band in the dorsal fin (Ref. 57549). Caudal fin membrane yellow, in breeding males with broad bands; pectoral fin completely black; dorsal fin base length 56.3-62.45% SL; 14-20 gill rakers on the ceratobranchial (Ref. 42940).

Biologie     Verklarende woordenlijst (bv. epibenthic)

Inhabits the sand/rock interface; territorial males construct bowers on sand slopes near rocky areas with distances between bowers approximately 2-7m; females gather in large schools, sometimes numbering more than a hundred individuals; foraging schools are about 2-3m off the bottom and feed on plankton in the water column and on benthic invertebrates; mouthbrooding females are found close to the bottom (Ref. 57549).

Levenscyclus en paargedrag Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven

Builds bowers on a sand slope near rocky area at depth of 16-25 m. Bowers are circular or oval in shape with slight depression on the center and a surrounding sand mound. These contain a stone usually at the deeper margin of the sand mound. The depression is usually deepest near the stone and spawning takes place at this deepest part.

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.3   ±0.4 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).
