Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino; salmastro benthopelagico; non migratori; distribuzione batimetrica 1 - 6 m (Ref. 130221). Temperate; 71°N - 43°N, 11°W - 55°E
Northeast Atlantic: north-western Europe.
Dimensione / Peso / Età
Maturità: Lm ?  range ? - ? cm
Max length : 22.0 cm SL maschio/sesso non determinato; (Ref. 4119)
Spine dorsali (totale) : 14 - 17. Front of body brassy-yellow in the male, with larger pectoral fins than in the female (Ref. 35388).
Body shape (shape guide): elongated.
Adults live solitary or in pairs in weedy, shallow coastal areas (Ref. 4119). Feed on small invertebrates (Ref. 4119). Males build a nest from algae and debris, using kidney excrete as glue. Spawning season is May to June. Females deposit 150 - 200 eggs in the nest and often die shortly afterwards (Ref. 9900). Males care for and defend the nest. Offsprings reach maturity in one year (Ref. 4645).
Males build, guard and aerate the nest where the eggs are deposited (Ref. 205). Also Ref. 53335.
