Description synthétique
Clés d'identification | Morphologie | Morphométrie
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).
