Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 6; Vertebrae: 29 - 30. This species is distinguished by the following characters: no scales before the pelvic fin; D1 VI; males with a dusky to black first dorsal fin and four prominent short, black vertical or oblique bars on the body; with a spine in the second dorsal and anal fins; head pores present (Ref. 118118).
Found from three sites within the sheltered waters/embayment of north-east Kangaroo
Island (northern Shoal Bay, Western Cove and upper American River). It apparently occupy a
narrow strip of habitat at the lower intertidal and start of the sub-tidal over sand and mud with broken shell and sometimes in association with sparse marine eel grass Zostera and the algae Hormosira, but appears not to occupy fringing ribbon weed Posidonia in clean sands of deeper water. Radiographs showed small shells (micro-molluscs) in the stomach content of most fish screened, suggesting a benthic predatory/omnivorous diet (Ref. 118118).
