Actinopterygii (ray-finned fishes) > Perciformes (Perch-likes) > Sparidae (Porgies)
Etymology: Diplodus: Greek, diploos = twice + Greek, odous = teeth (Ref. 45335 ) .  More on author: Linnaeus .

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; brackish; demersal; oceanodromous (Ref. 51243 ); depth range 0 - 50 m (Ref. 12460 ), usually 0 - 50 m (Ref. 13780 ).   Subtropical; 48°N - 36°S, 18°W - 42°E

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Mediterranean Sea, southwestern Black Sea; eastern Atlantic from Canary Islands and Madeira north to Brittany (France); Angola.

Length at first maturity / Size / Weight / Age

Maturity: L m   ? , range 25 - ? cm
Max length : 45.0 cm TL male/unsexed; (Ref. 3397 ); common length : 22.0 cm TL male/unsexed; (Ref. 3397 ); max. published weight: 1.9 kg (Ref. 40637 ); max. reported age: 10 years (Ref. 26328 )

Short description Morphology | Morphometrics

Dorsal spines (total): 11 - 12; Dorsal soft rays (total): 12-15; Anal spines : 3; Anal soft rays : 11 - 14. Body with 5 black and 4 grey vertical bands. Snout is longer than the eye diameter (Ref. 35388 ).

Biology     Glossary (e.g. epibenthic)

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 ). Feeds on shellfish and other benthic invertebrates which it picks from the sediment (Ref. 5377 ).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Sexes separate or protandrous (Ref. 4781 ). In some areas, this species occurs as a digynic hermaphrodite, that is, males and females developing from intermediate juveniles (Ref. 52202 ). However, protandry with possible digyny was later confirmed (Ref. 103751 ). Reaches sexual maturity at 2 years, with an approximate size of 17 cm. Spawning happens from January to March. Egg size 0.8-0.9 mm; larval length at hatching 2.6 mm. Also Ref. 28504.
