In 2001 “Kuno the killer catfish” was accused of swallowing a dachshund. It was a big story at the time, people were trying to catch the fish but failed. Two years later a big ass catfish was found dead, proclaimed to be Kuno, stuffed and is displayed in a museum to this day.
Yeah, every word is made up. Looks like this one is made up “from lonia, the ancient region (western Asia Minor) occupied by the lonian people” as it says in the graphic as well as the suffix “stan”, which you probably know from some other countries and “is Persian and Urdu for “place of” or “where one stands”” according to dictionary.com.
