Short description
Identification keys | Morphology | Morphometrics
Found on sand bottom (Ref. 2850). Adults feed on small crustaceans and fish (Ref. 4525). Oviparous, with planktonic larvae (Ref. 36492). Eggs are presumably contained in floating rafts (Ref. 36492).

Estimates based on models
Preferred temperature (Ref.
123201): 16.2 - 26, mean 20.1 °C (based on 49 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02291 (0.00925 - 0.05675), b=2.94 (2.72 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.0 ±0.65 se; based on food items.
Generation time: 3.7 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.3).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (33 of 100).
