Max length : 32.5 cm TL Männchen/unbestimmt; (Ref. 93899); 38.5 cm TL (female)
Common in eelgrass of bays and estuaries, sometimes taken in shallow offshore waters (Ref. 5316). Feeds on crustaceans (Ref. 6885). Females larger than males (R.C. de Graaf, pers. Comm., 2001; Ref. 93899). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
