T. orientalis is known by a number of common names. The United Nations Food and Agriculture Organization prefers the name flathead lobster, while the official Australian name is Bay lobster. [3] [4] In Australia, it is more widely known as the Moreton Bay bug after Moreton Bay, near Brisbane, Queensland. [4] In Singapore, both the flathead lobster and true crayfish are called crayfish. They are used in many Singaporean dishes. [5] [6] [7] [8] [9] The species is sometimes confused with the Balmain bug (Ibacus peronii) but it can be distinguished by the placement of the eyes: the eyes of I. peronii are near the midline, while those of T. orientalis are at the margin of the carapace. [10]

T. orientalis has a strongly depressed body and grows to a maximum body length of 25 centimetres (9.8 in), or a carapace length of 8 cm (3.1 in). [3]

Thenus orientalis has an Indo-West Pacific distribution, ranging from the east coast of Africa (southern Red Sea, to Natal) to China including the Persian Gulf, southern Japan, the Philippines and along the northern coast of Australia from Western Australia to Queensland. [3] They are also caught on a small scale off the shores of Malaysia and Singapore. [3]

Crayfish Freshwater crustaceans in the superfamilies Astacoidea and Parastacoidea

Crayfish are freshwater crustaceans resembling small lobsters. In some locations, they are also known as crawfish, craydids, crawdaddies, crawdads, freshwater lobsters, mountain lobsters, rock lobsters, mudbugs, or yabbies. Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills. Some species are found in brooks and streams, where fresh water is running, while others thrive in swamps, ditches, and paddy fields. Most crayfish cannot tolerate polluted water, although some species, such as Procambarus clarkii, are hardier. Crayfish feed on animals and plants, either living or decomposing, and detritus.

Moreton Bay

Moreton Bay is a bay located on the eastern coast of Australia 14 kilometres (8.7 mi) from central Brisbane, Queensland. It is one of Queensland's most important coastal resources. The waters of Moreton Bay are a popular destination for recreational anglers and are used by commercial operators who provide seafood to market.

<i>Jasus edwardsii</i> Species of crustacean

Jasus edwardsii, the southern rock lobster, red rock lobster, or spiny rock lobster, is a species of spiny lobster found throughout coastal waters of southern Australia and New Zealand including the Chatham Islands. This species is commonly called crayfish or crays in both Australia and New Zealand and kōura in Māori. They resemble lobsters, but lack the large characteristic pincers on the first pair of walking legs.

Lobster fishing Aspect of the fishing industry

Lobsters are widely fished around the world for their meat. They are often hard to catch in large numbers, but their large size can make them a profitable catch. Although the majority of the targeted species are tropical, the majority of the global catch is in temperate waters.

Slipper lobster Family of crustaceans

Slipper lobsters are a family (Scyllaridae) of about 90 species of achelate crustaceans, in the Decapoda clade Reptantia, found in all warm oceans and seas. They are not true lobsters, but are more closely related to spiny lobsters and furry lobsters. Slipper lobsters are instantly recognisable by their enlarged antennae, which project forward from the head as wide plates. All the species of slipper lobsters are edible, and some, such as the Moreton Bay bug and the Balmain bug are of commercial importance.

<i>Metanephrops challengeri</i> Species of crustacean

Metanephrops challengeri is a species of slim, pink lobster that lives around the coast of New Zealand. It is typically 13–18 cm (5–7 in) long and weighs around 100 g (3.5 oz). The carapace and abdomen are smooth, and adults are white with pink and brown markings and a conspicuous pair of long, slim claws. M. challengeri lives in burrows at depths of 140–640 m (460–2,100 ft) in a variety of sediments. Although individuals can live for up to 15 years, the species shows low fecundity, where small numbers of larvae hatch at an advanced stage.

<i>Ibacus peronii</i>

Ibacus peronii, the Balmain bug or butterfly fan lobster, is a species of slipper lobster. It lives in shallow waters around Australia and is the subject of small-scale fishery. It is a flattened, reddish brown animal, up to 23 cm (9 in) long and 14 cm (6 in) wide, with flattened antennae and no claws.

<i>Thalassina</i> Genus of lobsters

Thalassina is a genus of mud lobsters found in the mangrove swamps of the Indian Ocean and western Pacific Ocean. Its nocturnal burrowing is important for the recycling of nutrients in the mangrove ecosystem, although it is sometimes considered a pest of fish and prawn farms.

<i>Sagmariasus</i>

Sagmariasus verreauxi is a species of spiny lobster that lives around northern New Zealand, the Kermadec Islands the Chatham Islands and Australia from Queensland to Tasmania. It is probably the longest decapod crustacean in the world, alongside the American lobster Homarus americanus, growing to lengths of up to 60 centimetres (24 in).

<i>Scyllarides latus</i> Species of crustacean

Scyllarides latus, the Mediterranean slipper lobster, is a species of slipper lobster found in the Mediterranean Sea and in the eastern Atlantic Ocean. It is edible and highly regarded as food, but is now rare over much of its range due to overfishing. Adults may grow to 1 foot (30 cm) long, are camouflaged, and have no claws. They are nocturnal, emerging from caves and other shelters during the night to feed on molluscs. As well as being eaten by humans, S. latus is also preyed upon by a variety of bony fish. Its closest relative is S. herklotsii, which occurs off the Atlantic coast of West Africa; other species of Scyllarides occur in the western Atlantic Ocean and the Indo-Pacific. The larvae and young animals are largely unknown.

<i>Parribacus japonicus</i>

Parribacus japonicus, the Japanese mitten lobster, is a species of slipper lobster. Though the common name for this lobster is the Japanese mitten lobster, it is locally called zōri-ebi (ゾウリエビ) – zōri denoting the Japanese sandal it resembles, and ebi meaning shrimp or lobster.
