''Lucifer'' is a little-known and degenerate genus of prawns, the only genus in the family Luciferidae. ''Lucifer'' has a long body, but many fewer appendages than other prawns, with only three pairs of pereiopods remaining, all without claws. It also bears no gills. The females, uniquely among prawns, carry the fertilised eggs on her pleopods until they are ready to hatch. This parallels the development of a similar system in pleocyemates, although the attachment is less strong in ''Lucifer''.〔 The length of the eye-stalks and the form of the petasma are used in distinguishing the eight species from each other. Seven species are recognised: *''Lucifer chacei'' Bowman, 1967 *''Lucifer faxoni'' Borradaile, 1915 *''Lucifer hanseni'' Nobili, 1905 *''Lucifer intermedius'' Hansen, 1919 *''Lucifer orientalis'' Hansen, 1919 *''Lucifer penicillifer'' Hansen, 1919 *''Lucifer typus'' H.
