Etymology: Symphodus: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335). More on author: Risso.
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; reef-associated; depth range 1 - 30 m (Ref. 4742). Subtropical; 48°N - 30°N, 10°W - 42°E
Eastern Atlantic: Gulf of Gascogne to Gibraltar including the Mediterranean and Black Sea.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 5 - 7 cm
Max length : 17.0 cm SL male/unsexed; (Ref. 4742); common length : 12.0 cm SL male/unsexed; (Ref. 4742); max. reported age: 8 years (Ref. 4742)
Adults are found near rocks, mainly in eel-grass beds (Ref. 4742). Mainly solitary (Ref. 4742). Nest of seaweed built by male (Ref. 4742). Feed on mollusks, bivalves, gastropods, shrimps, sea-urchins and hydroids (Ref. 4742). Males grow faster than females (Ref. 4742). Oviparous, distinct pairing during breeding (Ref. 205).
Oviparous, distinct pairing during breeding (Ref. 205). Each male builds a nest of seaweed for one or two females to spawn in (Ref. 4742).
