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

Indo-Pacific: East Africa to the Hawaiian and Tuamoto islands. However, the Pacific population has been recognized as a distinct subspecies (Chaetodon trifasciatus lunulatus Quoy & Gaimard, 1825) by Burgess (Ref. 4855) while according to Randall, pers. comm. 1995, Chaetodon trifasciatus occurs only in the Indian Ocean, while Chaetodon lunulatus occurs only in the Pacific.

Biology     Glossary (e.g. epibenthic)

Occur in coral-rich lagoons and semi-protected seaward reefs. Territorial and aggressive to other Chaetodon. Small juveniles secretive in corals (Ref. 48636). Swim in pairs. Feed exclusively on coral polyps, particularly of the Pocillopora type (Ref. 5503, 48636). Oviparous (Ref. 205), monogamous (Ref. 52884). Form pairs during breeding (Ref. 205).

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=0.02455 (0.01593 - 0.03782), b=3.09 (2.96 - 3.22), based on LWR estimates for species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.6 se; Based on diet studies.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (K>1).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
Price category (Ref. 80766):   Unknown.
