 In 2003, archaeologist Brad Lepper suggested that the Alligator Effigy Mound in Granville, Ohio represents the underwater panther.Lepper posits that early European settlers, when learning from Native Americans that the mound represented a fierce creature that lived in the water and ate people, mistakenly assumed that the Native Americans were referring to an alligator.The "Grimm" episode "Mishipeshu" involves the possession of a young Native American by an underwater panther.
