Ecology of Diplodus sargus
 
Main Ref. Sala, E. and E. Ballesteros, 1997
Remarks Inhabits coastal rocky reef areas (Ref. 12460) and Posidonia oceanica beds. Like other sparids, it is very active and frequents the surf zone, primarily at dawn (Ref. 13780). Diurnal omnivore feeding on algae, sea-urchins, worms, gastropods and amphipods (Ref. 55064). Important predators of sea urchins in Azorean coastal habitats (Ref. 55064). Feeds on shellfish and other benthic invertebrates which it picks from the sediment (Ref. 5377).
