Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

Pacific Ocean: Mariana Islands to the Hawaiian and Society islands, south to Vanuatu and the Austral Islands. Possibly at Rowley Shoals (eastern Indian Ocean).

Adults found in exposed seaward reefs. Sometimes inhabit clear lagoons or channels. They occur in small to large aggregations on the upper edge of the slope over live coral or rubble. Uncommon (Ref. 9710). Benthopelagic (Ref. 58302). 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 of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01516 (-0.15937 - 0.18968), b=2.99232 (2.89639 - 3.08825), based on LWR estimates for this family-BS (Ref. 93245).

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

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low vulnerability (11 of 100) .

Price category (Ref. 80766): Unknown.
