Max length : 20.0 cm TL male/unsexed; (Ref. 30464); common length : 15.0 cm TL male/unsexed; (Ref. 30464)

Biology     Glossary (e.g. epibenthic)

Occurs inshore over reef areas (Ref. 7300). Swim either singly or in small schools, moving very rapidly and erratically, stopping occasionally to gulp down a few large planktonic crustaceans (Ref. 30464).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00589 - 0.03714), b=3.00 (2.78 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 71.6 [32.0, 139.8] mg/100g; Iron = 0.549 [0.295, 1.074] mg/100g; Protein = 18 [17, 19] %; Omega3 = 0.452 [0.223, 0.905] g/100g; Selenium = 7.92 [3.39, 18.76] μg/100g; VitaminA = 11.6 [2.4, 56.3] μg/100g; Zinc = 0.868 [0.552, 1.392] mg/100g (wet weight);
