Inhabit seaward reefs (Ref. 9710); apparently a deep dweller, collected and observed only on a small section of a well-developed coral reef ('The Bear', off Gannett Ridge, north side of Pitcairn); collected with spears and rotenone (Ref. 4858). Feed on zooplankton. Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02239 (0.01117 - 0.04486), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.45 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (14 of 100) .
