Orectolobus
''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 (the Japanese wobbegong, ''O. japonicus'') occurs as far north as Japan. They have a mottled or spotted Crypsis, cryptic pattern, and have elongated dermal lobes in the region near the mouth. Most have a maximum length of or less, but two species, ''Orectolobus halei, O. halei'' and ''Orectolobus maculatus, O. maculatus'', reach about (earlier reports of similar-sized ''Orectolobus ornatus, O. ornatus'' is due to confusion with ''O. halei''). These sluggish ambush predators are typically seen resting on the seafloor, and at least some species are nocturnal. While usually harmless to humans, they have been known to bite, but genera ...

Wobbegong
The 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 (the Japanese wobbegong, ''Orectolobus japonicus'') 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. Description Wobbegongs are bottom-dwelling sharks, spending much of their time resting on the sea floor. Most species have a maximum length of , but the largest, the spotted wobbegong, ''Orectolobus maculatus'', and banded wobbegong, ''O. halei'', reach about in length. Wobbegongs are well camouflaged with a symmetrical pattern of bold markings which resembles a carpet. Because of this striking pattern, wobbegongs and their close relatives a ...

Spotted Wobbegong
The spotted wobbegong (''Orectolobus maculatus'') is a carpet shark in the family Orectolobidae, endemic to Australia. It is a large, robust species, typically reaching 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 for commercially in Australia, but it is not severely threatened. It is listed as a least-concern species on the IUCN Red List. Taxonomy The species was described by Pierre Joseph Bonnaterre in 1778. He classified it in the genus ''Squalus'', with the full scientific name of ''Squalus maculatus''. Bonnaterre redescribed the species in 1788 in ''Orectolobus'', its current ge ...

Carpet Shark
Carpet sharks are sharks classified in the order Orectolobiformes . Sometimes the common name "carpet shark" (named so because many species resemble ornately patterned carpets) 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. Characteristics The carpet sharks are a diverse group of sharks with differing sizes, appearances, diets, and habits. They first appeared in the fossil record in the Early Jurassic; the oldest known orectolobiform genera are '' Folipistrix'' (known from Toarcian to Aalenian of Belgium and Germany), '' Palaeobrachaelurus'' (Aalenian to Barremian) and '' Annea'' (Toarcian to Bajocian of Europe). All species have two dorsal fins and a relatively short, transverse mouth that does not extend behind the eyes. Besides the nostrils are barbels, tactile sensory organs, ...

Tasselled Wobbegong
The tasselled wobbegong (''Eucrossorhinus dasypogon'') 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 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. During the day, the solitary tasselled wobbegong can generally be found lying inside caves or under ledges with its tail curled. Individual sharks tend to remain within a local area and have favored resting spots. While resting, it opportunistically ambushes nearby fishes and invertebrates, and also lures in prey by waving its tail to mimic the appearance of a small fish. At night, it emerges and actively forages for foo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Orectolobus Ornatus
The ornate wobbegong (''Orectolobus ornatus'') 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 . 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. Taxonomy The ornate wobbegong was described by Charles Walter De Vis in 1883. It was previously assumed to be the juvenile form of the Gulf wobbegong (''Orectolobus halei''), due to similarities between the two species. However, there are multiple differences: for example, the ornate wobbegong is smaller, has a smaller head relative to its body, and is less freckled. "Banded wobbegong ...

Orectolobus Hutchinsi
''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. Morphology Electrosensitivity Like all wobbegong sharks, the western wobbegong shark is able to electrosense, meaning that the shark can sense the electricity of moving organisms around it. T ...

(2006). Wobbegong sharks redescribed.'' Practical Fishkeeping ''Orectolobus halei'' is very similar to the ornate wobbegong, ''O. ornatus'', of which it was treated as a Synonym (taxonomy), synonym until 2006.Huveneers, C. (2006).

Japanese Wobbegong
The Japanese wobbegong (''Orectolobus japonicus'') 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. See also * List of sharks References * * Theiss, S. M., Collin, S. P. & Hart, N. S.
