Pineapple fish- light organ

Also known as the knight fish, (Cleidopus gloriamaris) is an attractive temperate water species. It can effectively live in aquaria for many years.

The light organ under each jaw has bioluminescent bacteria which glow in the dark, attracting small prey to the fish and the fish snaps them up.

Good infra red footage of pineapple fish feeding is available on Beneath Southern Seas (DVD) or Beneath the blue (VHS) by the same cinematographer George Evatt. The ffotage is quite remarkable and shows how these fish find their food.

Working with HMI lights: by Scuba Diver Australasia; HMI technology is not new. It evolved in the late 1960s when lamp developer Osram began producing HMI bulbs for the film industry at the request of German television seeking a less expensive alternative to incandescent lights. Ironically, HMI is now much more expensive than halogen and tungsten.
