Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 12; членистые (мягкие) лучи спинного плавника (общее число) : 12 - 13; колючие лучи анального плавника: 2; членистые (мягкие) лучи анального плавника: 12 - 13. Color in life white with 3 black bars; has a black area over the outer two-thirds of the tail, which distinguishes it from D. aruanus; pelvic fins black; pectoral fins transparent. Tubed lateral lines scales 16 to 17. Margins of preorbital, suborbital, and preoperculum finely serrated (Ref. 2746). Body depth 1.5-1.7 in SL (Ref. 90102).
Schooling species, adults inhabit sheltered lagoons, harbors and inlets. Also in somewhat open substrates with outcrops of Acropora corals (Ref. 48636). Often associated with small coral heads. Feed on a variety of plankton, including larval shrimps and crabs, algae, ostracods, amphipods, pelagic tunicates, copepods, and fish eggs. 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). Diurnal species (Ref. 54980; 113699).

Estimates based on models
Preferred temperature (Ref.
123201): 24.9 - 29, mean 27.8 °C (based on 648 cells).
Phylogenetic diversity index (Ref.

50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.00944 - 0.04623), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.36 se; based on food items.
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
