Eponymy: This is a toponym; the holotype was collected in the estuary of the Fitzroy River, Western Australia. (Ref. 128868), visit book page.

生態学
海; 汽水性の 底生の; 深さの範囲 0 - 40 m (Ref. 6871). Subtropical; 10°S - 26°S
Western Pacific: northern Australia, from Western Australia to Queensland. Recorded in the Arafura Sea (Ref. 9819).
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm 94.5, range 89 - 100 cm
Max length : 135 cm TL オス/雌雄の選別がない; (Ref. 6871)
背面の脊椎 (合計) : 0; 肛門の骨: 0. Bronze above, fading to grayish brown after death and in preserved specimens; light below, without conspicuous markings on fins; no conspicuous white band on flanks (Ref. 9997).
A little-known shark found inshore and offshore on the continental shelves from the intertidal to at least 40 m depth (Ref. 9997). Feeds mainly on teleost fishes, also crustaceans (Ref. 6871). Viviparous (Ref. 50449). Utilized for human consumption (Ref. 244, 9997) and probably for the oriental shark fin trade (Ref. 244).
Life cycle and mating behavior
