Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm TL male/unsexed; (Ref. 559); common length : 20.0 cm TL male/unsexed; (Ref. 559)
Common in estuaries and in association with Zostera and other vegetation. Juveniles associate with drifting seaweed (Ref. 12114, 12115). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Used in Chinese medicine (Ref. 12166).
