Short description Morphology | Morphometrics

Dorsal spines (total): 12 - 14; Dorsal soft rays (total): 21-23; Anal spines: 3; Anal soft rays: 16 - 17. Body color is white with 4-5 chevron-shaped blackish bands on the sides.

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

Pacific Ocean: Ryukyu Islands to the Philippines and extending to Lord Howe, Rapa and Tuamoto islands. Replaced by Chaetodon madagascariensis in the Indian Ocean, Chaetodon xanthurus in southeast Asia, and Chaetodon paucifasciatus in the Red Sea (Ref. 37816).

Inhabit deep lagoons and seaward reefs. Occur singly or in pairs. Feed on algae and small benthic invertebrates (Ref. 1602). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205). May hybridize with C. xanthurus.

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=0.02250 (-0.07795 - 0.12296), b=3.24235 (3.17298 - 3.31171), based on LWR estimates for species & genus-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.0 ±0.41 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 (10 of 100) .

Price category (Ref. 80766): Unknown.
