Lucifer is a little-known and degenerate genus of prawns, the type genus of the family Luciferidae. [2] 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. [3] 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. [3] The length of the eye-stalks and the form of the petasma has been used in distinguishing the species, including before some were later moved into another genus Belzebub .
The name Lucifer is Latin for "light bearer" was given to the genus because of these prawns' bioluminescence. [4]
Two species are recognised:
Five nominal Lucifer species (L. chacei, L. faxoni, L. hanseni, L. intermedius, and L. penicillifer) have been reclassified in a distinct genus, Belzebub . [4]
