Fish-pineapple or Australian kishechnik (Cleidopus gloriamaris)

Australian kishechnik has in common several names, and all of them are connected with the appearance of this marine life.

The English call it fish-pineapple because of coloring and body shape. Each of fairly large flakes fish has a yellow color with black outline, which is very like a pineapple rind.

Another name for the Australian kishechnika sounds like “fish knight”. It is due to the fact that each lamella has a spinous process, making the fish seem as if clad in armor like a knight.
