Biology     Glossary (e.g. epibenthic)

Usually seen in clear-water areas at depths below 15 m, and prefers islands and offshore reefs rather than continental shores. Feeds mainly on fishes, and on crabs, shrimps and stomatopods. It is highly appreciated for the quality of its flesh. It may not be sold in Mauritius because of cases of ciguatera poisoning (Ref. 11888). In the Hong Kong live fish markets (Ref. 27253).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00671 - 0.01560), b=3.04 (2.92 - 3.16), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.3   ±0.7 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.18).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (49 of 100) .
Price category (Ref. 80766):   Very high.
