Mediterranean Sea: Eastern Atlantic: Along the coast of Portugal to the Gulf of Guinea (St. Thomas Island = São Tomé Island), may also reach Angola. Quoted mainly in the islands (Azores, Salvage, Canary, Annobon, etc.) than on the continent.
Length at first maturity / Size / Gewicht / Alter
Maturity: Lm ?, range 7 - 7.3 cm
Max length : 25.0 cm TL Männchen/unbestimmt; (Ref. 10797); common length : 13.0 cm TL Männchen/unbestimmt; (Ref. 10797)
Rückenflossenstacheln (insgesamt) : 14; Rückenflossenweichstrahlen (insgesamt) : 9 - 11; Afterflossenstacheln: 2; Afterflossenweichstrahlen: 9 - 11.
Adults form small shoals in midwater above or near rocky reefs or above seagrass meadows (Posidonia. They feed on small planktonic or benthic animals (Ref. 6760). Reproduce in summer (Ref. 6760). Eggs characterized by adhesive filaments are nested on rocky or sandy bottoms (Ref. 6760). Males guard the eggs (Ref. 6760).
Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Breed on rocky or sandy bottoms (Ref. 6760). Males guard the eggs (Ref. 6760).
