Cleidopus gloriamaris is a sole member of its genus, also known as the pineapplefish it is native to coastal waters off Queensland, New South Wales, and Western Australia. It is often observed by divers on shallow coastal reefs, but is also trawled in deeper offshore waters.
The Pineapplefish is named for its pineapple-like appearance. It has robust yellow to whitish scales with black margins. On either side of the lower jaw is a light organ (photophores) that produces a greenish glow. The colour of the light is reported to change to red as the fish ages. The light of the pineapplefish is produced by symbiotic colonies of the luminescent bacteria Vibrio fischeri within its photophores.
The Pineapplefish feeds at night. Its prey are detected by light emitted from the light organs on the sides of the lower jaw. Within the light organs symbiotic bacteria produce a greenish glow.
Monocentrus japonicus, the similar Japanese Pineapplefish, also occurs in Australian waters. It can be distinguished from the Pineapplefish by its more rounded snout.
