Maturity: Lm ? range ? - ? cm
Max length : 33.0 cm TL maschio/sesso non determinato; (Ref. 6330); common length : 17.0 cm TL maschio/sesso non determinato; (Ref. 6330)
Inhabits seagrass beds in bays and estuaries, but also enters fresh water (Ref. 7251). Resident in estuaries during spring through fall, migrates into near shore continental shelf waters during winter. Found in waters of 4-17 °C. Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
