Biologie     Verklarende woordenlijst (bv. epibenthic)

Inhabits area of extensive gradual slopes of clean white sand (in 30-35 m depth). Collected from sites located in channel passes from the outer reef to extensive inner lagoons, and were hence subject to frequent strong currents and high rates of water exchange (Ref. 116128).

Schattingen op basis van modellen

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00347 - 0.01582), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.0   ±0.3 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Kwetsbaarheid van de visserij (Ref. 59153):  Low vulnerability (10 of 100). 🛈
