Parapriacanthus
''Parapriacanthus'' is a genus of sweepers native to the Indian Ocean and the western Pacific Ocean. ''Parapriacanthus'' are bioluminescent, with ventral light organs for counter-illumination. ''Parapriacanthus'' luciferase is a kleptoprotein, obtained from their diet on bioluminescent ostracods. Species There are currently 11 recognized species in this genus: * ''Parapriacanthus argenteus'' ( von Bonde, 1923) * ''Parapriacanthus darros'' J. E. Randall & Bogorodsky, 2016 * '' Parapriacanthus dispar'' ( Herre, 1935) (Deep bullseye) * '' Parapriacanthus elongatus'' ( McCulloch, 1911) (Slender bullseye) * ''Parapriacanthus guentheri ''Parapriacanthus'' is a genus of sweepers native to the Indian Ocean and the western Pacific Ocean.

Kleptoprotein
A kleptoprotein is a protein which is not encoded in the genome of the organism which uses it, but instead is obtained through diet from a prey organism. Importantly, a kleptoprotein must maintain its function and be mostly or entirely undigested, drawing a distinction from proteins that are digested for nutrition, which become destroyed and non-functional in the process. This phenomenon was first reported in the bioluminescent fish '' Parapriacanthus'', which has specialized light organs adapted towards counter-illumination, but obtains the luciferase enzyme within these organs from bioluminescent ostracods, including '' Cypridina noctiluca'' or '' Vargula hilgendorfii''. See also * Kleptoplasty Kleptoplasty or kleptoplastidy is a symbiotic phenomenon whereby plastids, notably chloroplasts from algae, are sequestered by host organisms. The word is derived from ''Kleptes'' (κλέπτης) which is Greek for thief. The alga is eaten normal ... References {{biology-stub B ...
