Pineapple Fish

Pineapple Fish
Cleidopus gloriamaris

The Pineapple fish is aptly named because it looks similar to the fruit known as a pineapple. These amazing fish are able to emit a glow that is illuminated by bacteria produced by a gland in the jaw making them prominently yellow in colour. This adaptation is to attract various microscopic organisms that will soon be preyed upon. The Pineapple fish are a favourite in many aquariums across the world.
