T. orientalis is known by a number of common names. The United Nations Food and Agriculture Organization prefers the name flathead lobster, while in Australia, it is more widely known as the Moreton Bay bug after Moreton Bay, Brisbane, Queensland. [3] In Singapore, both the flathead lobster and true crayfish are called crayfish. They are used in many Singaporean dishes. [4] [5] [6] [7] [8] 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. [9]

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). [10]

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. [10] They are also caught on a small scale off the shores of Malaysia and Singapore. [10]

<span class="mw-page-title-main">Crayfish</span> Freshwater crustaceans

Crayfish are freshwater crustaceans belonging to the infraorder Astacidea, which also contains lobsters. 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.

<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. It is commonly called crayfish in Australia and New Zealand and kōura in Māori. They resemble lobsters, but lack the large characteristic pincers on the first pair of walking legs.

<span class="mw-page-title-main">Lobster fishing</span> 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 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>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.
