Biology     Glossary (e.g. epibenthic)

Inhabits seagrass beds and sandy areas of lagoons and outer reef slopes. Found singly or in schools. Feeds mainly on crustaceans, mollusks, and fish. Marketed fresh (Ref. 9775).

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

Gonochorism is inferred for this species as sizes of males and females overlapped and male gonad morphology is typical of secondarily derived testes (Ref. 103751). Juvenile hermaphroditism is exhibited by this species (Ref. 35994).

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 25.1 - 29.3, mean 28.6 (based on 2744 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.01017 - 0.02470), b=3.01 (2.88 - 3.14), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.8   ±0.0 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.29-0.31; tm=3.7-5; tmax=24).
Prior r = 0.42, 2 SD range = 0.26 - 0.67, log(r) = -0.87, SD log(r) = 0.24, Based on: 4 K, 2 tgen, 1 tmax, records
Vulnerability (Ref. 59153):  Moderate vulnerability (38 of 100) .
Price category (Ref. 80766):   Very high.
