Flathead Lobster
Thenus orientalis
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.
