More Info
Distribution |
Dampier Archipelago, Western Australia, around the tropical north to Moreton Bay, Queensland. Juveniles may occur as far south as the Perth region on the west coast. Elsewhere the species occurs in the Indo-west Pacific from the Red Sea and East Africa eastward through northern Australia to New Caledonia, northward to southern Japan. It has also spread to the Mediterranean, via the Suez Canal. The species usually inhabits coastal slopes and sheltered muddy to sandy substrates in deeper offshore waters. Individuals are also seen near shallow macroalgal and seagrass beds with silty rubble substrates, and areas of part-destroyed coral reefs, and rocky outcrops. |
Features |
Dorsal fin 9; Anal fin 9; Pectoral fin 10. |
Feeding |
Feeds on macroalgae and benthic invertebrates, including polychaete worms, crustaceans, molluscs, and sponges. |
Remarks |
The flesh and internal organs are considered poisonous (Matsuura 2010). |
Similar Species |
The similar Smallspine Turretfish, Tetrosomus reipublicae, differs in having a moderately elevated dorsal ridge with two small spines on the middle part, a straight to slightly concave snout, and a truncate to slightly rounded caudal fin. |
