Thenus

Common card · No. 274450

Thenus orientalis is a species of slipper lobster from the Indian and Pacific oceans. 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 (often shortened to just bug) after Moreton Bay, Brisbane, Queensland. In Singapore, both the flathead lobster and true crayfish are called crayfish. They are used in many Singaporean dishes. 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. 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). Thenus orientalis has an Indo-West Pacific distribution, ranging from the east coast of Africa (southern Red Sea, to Natal) to China...
