Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 15; Rückenflossenweichstrahlen (insgesamt) : 10; Afterflossenstacheln: 1; Afterflossenweichstrahlen: 18; Wirbelzahl: 35. This species is distinguished from its congeners in having the following characters: D1 III, D2 XII, D3 10; A I,18; lateral line discontinuous, first series with 16-18 pored scales, second series 15-17 notched scales; mandibular pore system 4+1+4; supraorbital cirrus simple and slender; nasal cirrus short and broad; body pink to light orange with 4 vertical or slightly oblique deep brown bars from behind pectoral fin base to caudal fin base, each broad bar edged with whitish border; caudal fin is pale with a brownish-black streak near its distal margin; indistinct sexual dichromatism, with spawning males possessing a blackish anal fin and spotted with melanophores on body, head, dorsal and pectoral fin rays (Ref. 79877).
Female members of the Tripterygiidae have eggs that are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00258 - 0.01228), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.3 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).
