Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino; acqua dolce; salmastro demersale; amfidromo (Ref. 46888); distribuzione batimetrica 0 - 15 m (Ref. 45332). Subtropical; 8°C - 24°C (Ref. 4944); 60°N - 12°N, 32°W - 42°E
Eastern Atlantic: western Scotland to Senegal. Also known from the Mediterranean and Black Sea. Lessepsian migrant to the Red Sea (Ref. 5299). Records from Pointe Noire and vicinity might be doubtful.
Lunghezza alla prima maturità / Dimensione / Peso / Età
Maturità: Lm 6.5, range 6 - 7 cm
Max length : 13.0 cm TL maschio/sesso non determinato; (Ref. 49698); Età massima riportata: 10 anni (Ref. 35388)
Neck naked. No black spots in the front end of each dorsal fin (Ref. 35388).
Body shape (shape guide): fusiform / normal.
Predominantly marine, but may enter freshwater. Adults occur inshore in intertidal waters, under stones and in pools on sheltered rocky shores with much weed cover. Macrobenthos feeder on hard substrates (Ref. 92840), they feed on crustaceans (larger amphipods, isopods, small crabs) and polychaetes; juveniles eat harpacticoid copepods, amphipods, polychaetes and mites (Ref. 4696). Oviparous (Ref. 205). Fusiform shaped eggs are found in patches of several thousand on undersurface of stones, shells, polychaete tubes or Ciona mantles (Ref. 4696).
Oviparous (Ref. 205). Male guards the eggs deposited by the female under rocks or inside empty bivalve shells until they hatch (Ref. 45332). Larvae remain near the substrate until they assume the cryptobenthic behavior of the adults (Ref. 45332). Are repeat spawners (Ref. 4696).
