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

Indo-Pacific: Sri Lanka (Ref. 10361) and Cocos-Keeling Islands to the Hawaiian, Marquesan and Tuamoto islands, north to southern Japan, south to Rowley Shoals and New South Wales, Australia.

Occur in lagoons and seaward reefs to a depth of 30 m, prefer coral-rich and clear water areas (Ref. 205). Benthopelagic (Ref. 58302). Encountered singly, in pairs or small groups (adults often in pairs; juveniles solitary and inshore). Feed on filamentous algae, small invertebrates, coral polyps, and fish eggs. Oviparous (Ref. 205). Form pairs during breeding (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=0.02252 (-0.08454 - 0.12958), b=3.01852 (2.94654 - 3.09049), based on LWR estimates for species & genus-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.1 ±0.3 se; Based on diet studies.

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

Vulnerability (Ref. 59153): Low vulnerability (23 of 100) .

Price category (Ref. 80766): Unknown.
