Trophic Strategy

provided by Fishbase
Specimens from northwestern Africa feed primarily on faunal organisms, especially polychaetes (90% of contents) and a variety of small crustaceans. Smaller individuals (30-40 mm head length) feed mostly on epibenthic organisms, especially the copepod Aetidopsis carinata.
