Card Trivia:Depth Gardna


 * This monster is based on an Ammonite, a type of extinct nautiloid famous for its distinct boney shells, which are a common find at fossil sites.
 * This monster may also be based on the Nautilus, the living descendants of the Ammonite. This is hinted at by this card's name "Depth Guardna"– the Nautilus lives in the ocean deep, while Ammonites dwelled in the open ocean.


 * This monster bears an incredibly strong resemblance to "Arma Knight"– which is also based on the Ammonite– by its having the same body type, shell, type and Attribute.
