Biology     Glossary (e.g. epibenthic)

Occurs in lagoon and seaward reefs. Feeds exclusively on the polyps of the tubular Acropora corals. Swims in pairs and are territorial. Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Distinct pairing (Ref. 205). Monogamous mating is observed as both obligate and social (Ref. 52884).

Estimates based on models

Preferred temperature (Ref. 115969): 25.2 - 29.3, mean 28.6 °C (based on 2473 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02344 (0.01269 - 0.04331), b=3.00 (2.84 - 3.16), in cm total length, based on LWR estimates for species & Genus-BS (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.61 se; based on food items.
Generation time: 1.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (14 of 100) .
Climate Vulnerability (Ref. 125649):   (0 of 100) .
