Biology     Glossary (e.g. epibenthic)

Adults are found in the sublittoral zone and may enter semi-enclosed sea areas (Ref. 11230). In Guam, it is encountered in large numbers around fish aggregating devices, buoys anchored offshore to attract pelagic game fishes.

Estimates based on models

Preferred temperature (Ref. 123201): 22.7 - 29, mean 28 °C (based on 892 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01202 (0.01016 - 0.01423), b=2.97 (2.94 - 3.00), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.45 se; based on food items.
Generation time: 1.2 (1.0 - 1.4) years. Estimated as median ln(3)/K based on 24 growth studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (K=0.85; assumed tm=1).
