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

Indo-Pacific: East Africa, including the Mascarene Islands (Ref. 37792) to the Tuamoto Islands, north to Ryukyu Islands, south to southern Great Barrier Reef. Not occurring in the Red Sea.

Biology     Glossary (e.g. epibenthic)

Occurs in clear lagoon and seaward reefs around isolated coral heads. Solitary or in small groups (Ref. 90102). Prefers sandy bottoms of bays and lagoons rather than the coral reefs like most other Acanthuridae. The species is sometimes poisonous (Ref. 4795). Caught with nets (Ref. 30573).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02818 (0.01827 - 0.04349), b=2.88 (2.75 - 3.01), based on LWR estimates for species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±0.40 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (25 of 100) .
Price category (Ref. 80766):   Medium.
