More Info
Distribution |
Endemic to the southern half of Australia from Hervey Bay, Queensland, south to off Flinders Island, Bass Strait, Tasmania, and west to Norwegian Bay, Western Australia. Inhabits bays, macroalgal-covered reefs, coral reef lagoons, reef flats, reef faces and reef channels, and around offshore islands. This nocturnal species rests in caves, under ledges, in trenches, and on large sponges during the day. |
Biology |
Males mature at 1684-1819 mm TL, females mature at 1605-1871 mm TL. Females give birth to large litters (17-47 pups) in Spring, following a gestation period of about 10–11 months. |
Fisheries |
Taken in commercial and recreational fisheries as a target species and as bycatch. Historically, the skin was used as decorative leather. |
Remarks |
Orectolobus halei was previously synonymised thought to be the adult form of Orectolobus ornatus. |
Similar Species |
The Gulf Wobbegong, Orectolobus halei, differs from the Banded Wobbegong, Orectolobus ornatus, in having black edges around the saddles and fewer freckles, larger adult size (greater than 120 cm TL), more dermal lobes at the posterior preorbital group (4–6), precaudal vertebrae count (>106), spiral valve count (>25), and two supraorbital knobs. O. halei also has a shorter pelvic fin to anal fin interspace, larger pectoral fins, larger head dimensions, and relatively larger claspers in mature males. O. halei differs from the Spotted Wobbegong. O. maculatus, in having fewer (4-6) dermal lobes at the posterior preorbital group, and a distinctive brownish upper body with well-defined, darker brown saddles surrounded by black edges, saddles containing paler markings that lack whitish rings and blotches (unlike O. maculatus). |
Etymology |
The species is named halei in honour of Herbert M. Hale, a former director of the South Australian Museum. |
