Biology     Glossary (e.g. epibenthic)

Inhabits shallow water (10 m) on mud and sand bottoms of coastal zones (Ref. 9774) to a depth of 150 m (Ref. 9494). Feeds on small benthic animals (Ref. 9774). Caught mainly with prawn trawls (Ref. 9774). Marketed fresh and considered a good food fish.

Estimates based on models

Preferred temperature (Ref. 123201): 24.6 - 28.8, mean 27.7 °C (based on 564 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00343 - 0.01604), b=3.17 (3.00 - 3.34), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.37 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (39 of 100).
