The Pineapplefish is an unusual fish that can produce light from organs on the lower jaw.
The Pineapplefish is named for its pineapple-like appearance. It has robust scales with black margins. On either side of the lower jaw is a light organ that produces a greenish glow. The colour of the light is reported to change to red as the fish ages.
It is often observed by divers on shallow coastal reefs, but is also trawled in deeper offshore waters.
The species is recorded from the east and west coasts of Australia, but not from Victoria and South Australia.

Feeding and diet
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.
