Environment / Climate / Range
Marine; freshwater; brackish; demersal; amphidromous? (Ref. 51243); depth range ? - 5 m (Ref. 6733). Subtropical; 22°C - 24°C (Ref. 2059); 45°N - 30°N, 10°W - 42°E
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 21.0 cm TL male/unsexed; (Ref. 6733)
Eastern Atlantic: southern Biscay to Gibraltar, and also the Mediterranean and Black seas. Introduced and became established in the former USSR. In Appendix III of the Bern Convention (protected fauna).
Euryhaline, found among detritus or vegetation over sand or mud, within a temperature range of 8° to 24°C. Probably an amphidromous species (Ref. 51243) but migratory behavior needs verification. Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Early free-living young measure 23 mm TL (Ref. 6733).
