The various species of silver biddies found in Australian estuaries and inshore areas have similar brain locations to the common silver biddy. They should be killed humanely by iki jime, or in an ice slurry, or by a knock to the head.
- These fish have silver coloured bodies and highly protrusible jaws. The dorsal fin is long based with the anterior spines longer than those in the rest of the fin.
- Both jaws can protrude out and down forming a tube which is used to suck up sand or mud when the fish feeds on bottom-dwelling invertebrates.
- This species occurs in estuaries and shallow coastal waters throughout the tropical Indo-West Pacific region.
- In Australia they can be encountered from south Western Australia, around the tropical north of the country, and along the entire east coast to southern New South Wales.
Fish Size Common Length:
10-15 cm, maximum size around 25 cm.
