The Gulf wobbegong or banded wobbegong (Orectolobus halei) is a species of carpet shark in the family Orectolobidae, found in southern Australia between Southport, Queensland and Norwegian Bay, Western Australia. [2]

Contents

Orectolobus halei is very similar to the ornate wobbegong, O. ornatus, of which it was treated as a synonym until 2006. [3] Despite this, genetic evidence suggests that O. halei is more closely related to the largely sympatric spotted wobbegong, O. maculatus, than either are to the generally more northern O. ornatus. [4]

Compared to O. ornatus, O. halei has more dermal lobes at the posterior preorbital group, a shorter pelvic fin to anal fin interspace, larger pectoral fins, a larger head and larger claspers when mature. [3] It also reaches a significantly larger size, growing to a maximum length of 2.9 metres (9.5 ft), while O. ornatus only reaches 1.17 metres (3.8 ft). [1]

Reproduction is ovoviviparous.

Etymology

The shark is named in honor of Herbert M. Hale (1895-1963) then the Director of the South Australian Museum. [5]

Conservation Status

As of October 31, 2021, O. halei has been categorized as Fully Recovered by the IUCN. [6]

<span class="mw-page-title-main">Carpet shark</span> Order of sharks

Carpet sharks are sharks classified in the order Orectolobiformes. Sometimes the common name "carpet shark" is used interchangeably with "wobbegong", which is the common name of sharks in the family Orectolobidae. Carpet sharks have five gill slits, two spineless dorsal fins, and a small mouth that does not extend past the eyes. Many species have barbels.

<span class="mw-page-title-main">Wobbegong</span> Family of sharks

Wobbegong is the common name given to the 12 species of carpet sharks in the family Orectolobidae. They are found in shallow temperate and tropical waters of the western Pacific Ocean and eastern Indian Ocean, chiefly around Australia and Indonesia, although one species occurs as far north as Japan. The word wobbegong is believed to come from an Australian Aboriginal language, meaning "shaggy beard", referring to the growths around the mouth of the shark of the western Pacific.

<span class="mw-page-title-main">Cobbler wobbegong</span> Species of shark

The cobbler wobbegong, Sutorectus tentaculatus, is a carpet shark in the family Orectolobidae, the only member of the genus Sutorectus. It is found in the subtropical eastern Indian Ocean around Western Australia between latitudes 26° S and 35° S. It is frequently found in rocky and coral reef areas. Cobbler wobbegongs reach a length of 92 cm. It has unbranched dermal lobes on the head, rows of warty tubercles along the back and black spots on the body and fins.

<span class="mw-page-title-main">Tasselled wobbegong</span> Species of shark

The tasselled wobbegong is a species of carpet shark in the family Orectolobidae and the only member of its genus. It inhabits shallow coral reefs off northern Australia, New Guinea, and adjacent islands. Reaching 1.8 m (5.9 ft) in length, this species has a broad and flattened body and head. Its most distinctive trait is a fringe of branching dermal flaps around its head, which extends onto its chin. The fringe, along with its complex color pattern of small blotches and reticulations, enable it to camouflage itself against the reef environment.

<span class="mw-page-title-main">Japanese wobbegong</span> Species of shark

The Japanese wobbegong is a carpet shark in the family Orectolobidae of the wobbegong family, found in the tropical western Pacific Ocean from Japan and Korea to Viet Nam and the Philippines, between latitudes 43 and 6°N. It reaches a length of 1 m. Japanese wobbegong sharks typically remain motionless during the daytime, and are not active hunters. They use camouflage and their electroreceptor pores on their dorsal area to help them sense prey nearby.

<span class="mw-page-title-main">Spotted wobbegong</span> Species of shark

The spotted wobbegong is a carpet shark in the family Orectolobidae, endemic to Australia. It is a large, robust species, typically reaching 150–180 centimetres (59–71 in) in length. Coloured green, yellow, or brown, it has distinctive O-shaped spots throughout its body. It is nocturnal, resting at day and feeding on fish and invertebrates at night. An ovoviviparous species, the spotted wobbegong gives birth in the spring, during which time males can act aggressively towards other males and females. It has been known to bite humans, sometimes unprovoked, which can produce severe wounds. The species is fished commercially in Australia, but it is not severely threatened. It is listed as a least-concern species on the IUCN Red List.

<span class="mw-page-title-main">Ornate wobbegong</span> Species of shark

The ornate wobbegong is a species of carpet shark that lives in Australia and possibly other countries in the Western Pacific Ocean. It is coloured golden brown, yellow-green and blueish-grey, and it grows to maximum 120 centimetres (3.9 ft). Described by Charles Walter De Vis in 1883, it is similar in appearance to other Australian wobbegongs and has previously been classified as the same species as the Gulf wobbegong. It is a nocturnal species, hunting at night, and it can bite humans when disturbed. The International Union for Conservation of Nature has listed it as a least-concern species.

<span class="mw-page-title-main">Northern wobbegong</span> Species of shark

The northern wobbegong is a carpet shark in the family Orectolobidae, found in the western Pacific Ocean around Australia, between latitudes 9° S to 26° S. It reaches a length of 63 cm.

<i>Orectolobus hutchinsi</i> Species of shark

Orectolobus hutchinsi, the western wobbegong, is a species of carpet shark in the family Orectolobidae. The western wobbegong shark is a moderate sized marine shark found off the coast of Western Australia. Its scientific name is Orectolobus hutchinsi, and it was first identified in 1983 by Dr. Barry Hutchins, but was only recently classified, described, and published in 2006. O. hutchinsi is found on the shallow continental shelf in Western Australia from Coral Bay to Groper Bluff. This species is distinct from other wobbegong sharks because the western wobbegong shark has a yellowish brown upper body and darker brown saddles on their backs. Unlike other wobbegong sharks from the same area, the western wobbegong shark does not have white rings or blotches on their backs.

<i>Orectolobus</i> Genus of sharks

Orectolobus is a genus of carpet sharks in the family Orectolobidae. They are commonly known as wobbegongs, although this name also applies to the other members of the family. They are found in shallow temperate and tropical waters of the western Pacific Ocean and eastern Indian Ocean, chiefly around Australia and Indonesia, although one species occurs as far north as Japan.

Orectolobus reticulatus, the network wobbegong, is a recently described species of carpet shark found in relatively shallow waters off Kimberley and Darwin in north-western Australia. With a known maximum length of only 52.3 centimetres (20.6 in), it may be the smallest species of wobbegong. Until its description in 2008, it had been confused with the northern wobbegong. The network wobbegong has a short snout, broad head, elongated body, and two dorsal fins, with the first being slightly larger than the second. Its body is grayish brown with darker brown markings and a pale yellow underbelly. The network wobbegong lives in shallow waters along reefy bottoms.

<i>Hemiscyllium galei</i> Species of shark

Hemiscyllium galei, the Cenderawasih epaulette shark, is a species of bamboo shark in the family Hemiscylliidae. Together with H. henryi, it was only scientifically described in 2008 by Gerald R. Allen and Mark V. Erdmann. At present, H. galei is only known from depths of 2 to 4 metres at reefs in the Cenderawasih Bay in West Papua, Indonesia. The largest known specimen was 56.8 centimetres (22.4 in) long. It can be separated from its relatives by the combination of seven relatively large dark spots along the side of the body, white markings on the edge of its dark dorsal saddles and other scattered white spots on the upper side.
