Biology     Glossary (e.g. epibenthic)

Found in coastal waters, over sand muddy bottom. Juveniles enter estuaries. Adults feed on pelagic fishes at night. Often caught with Umbrina canariensis. Feeds on pelagic fish such as mackerel and horse mackerel (Ref. 36731). Marketed fresh, flesh highly esteemed (Ref. 9772).

Estimates based on models

Preferred temperature (Ref. 123201): 14 - 26.5, mean 18.7 °C (based on 131 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00413 - 0.01752), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.5   ±0.80 se; based on food items.
Generation time: 4.1 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
