Etymology: Diplodus: Greek, diploos = twice + Greek, odous = teeth (Ref. 45335).
Lebensraum / Klimazone / Range
Ökologie
; seewasser; brackwasser demersal; ozeanodrom (Ref. 51243); tiefenbereich 0 - 50 m (Ref. 12460), usually 0 - 50 m (Ref. 13780). Subtropical, preferred 23°C (Ref. 107945); 48°N - 36°S, 18°W - 42°E
Eastern Atlantic: Mediterranean and Black Sea. Eastern Central Atlantic: Madeira Island (Ref. 74541).
Length at first maturity / Size / Gewicht / Alter
Maturity: Lm ?, range 25 - ? cm
Max length : 45.0 cm TL Männchen/unbestimmt; (Ref. 3397); common length : 22.0 cm TL Männchen/unbestimmt; (Ref. 3397); max. veröff. Gewicht: 1.9 kg (Ref. 40637); max. veröff. Alter: 10 Jahre (Ref. 26328)
Rückenflossenstacheln (insgesamt): 11 - 12; Rückenflossenweichstrahlen (insgesamt): 12-15; Afterflossenstacheln 3; Afterflossenweichstrahlen: 11 - 14. Body with 5 black and 4 grey vertical bands. Snout is longer than the eye diameter (Ref. 35388).
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).
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.
