Lucifer hanseni Nobili, 1905 Lucifer inermis Borradaile, 1915 Belzebub hanseni, the ghost shrimp or ghost prawn, is a small planktonic and benthic species of prawn from the family Luciferidae.

The carapace is extremely laterally compressed and the head section is longer and narrower than the thorax which causes the eyes and antennae being widely separated from the mouthparts.

It was originally found in Egyptian waters in the 1920s but then apparently was not recorded until 2008-2011 when numbers were found off the coasts of Israel suggesting that the widening of the Suez Canal had allowed B. hanseni to establish a population in the Mediterranean, the process known as Lessepsian migration.

[2] They are predators of tiny planktonic crustaceans for which their third pereiopod is adapted to capture by having thick, curved spines which cover the limb.

[4] Belzebub hanseni was originally named as Lucifer hanseni by the Italian carcinologist Giuseppe Nobili after its bioluminescent properties, Lucifer means light bearer and after Hans Jacob Hansen a Danish zoologist who described many collections of several crustacean taxa collected by expeditions.
