Historical Background
The clionidae in Final Fantasy XI are based on the animal known as a clione, but they are named (likely accidentally) after a family of sponges.

Clionidae (singular form: clione; plural/scientific name: Clionidae) are a family of mollusks known as sea angels, which are floating sea slugs. They have transparent, gelatinous bodies and propel themselves through the waters of the ocean with "wings" (actually flaps). Small creatures, they rarely get over 2" (5cm) in length. They tend to be found in the cold waters of the Arctic and Southern Oceans, as well as the northern parts of the Atlantic and Pacific Oceans.

Clionids (singular form: clionid; plural form: clionids; scientific name: Clionaidae or Clionidae) are a family of massive sponges.
