The One Thousand and One Nights collection includes several tales featuring "sea people", such as "Djullanar the Sea-girl".[11] Unlike depictions of mermaids in other mythologies, these are anatomically identical to land-bound humans, differing only in their ability to breathe and live underwater. They can (and do) interbreed with land humans, and the children of such unions have the ability to live underwater. In the tale "Abdullah the Fisherman and Abdullah the Merman", the protagonist Abdullah the Fisherman gains the ability to breathe underwater and discovers an underwater society that is portrayed as an inverted reflection of society on land. The underwater society follows a form of primitive communism where concepts like money and clothing do not exist. In "The Adventures of Bulukiya", the protagonist Bulukiya's quest for the herb of immortality leads him to explore the seas, where he encounters societies of mermaids.[11]
Due to their vaguely anthropomorphic shape, dried skates have long been described as mermaids. Often their appearance is deliberately modified to make them look even more human. In Europe, dried skates, sometimes called devil fish, (not to be confused with devil fish or devil rays, two species of ray native to the north Atlantic) were displayed as mermaids, angels, demons, or basilisks. In Britain they are known as Jenny Hanivers, perhaps in reference to Antwerp, where they were made by sailors. Dried skates are also known in Mexico, where they are believed to have magical powers, and are used in healing rituals.[12]
