The listing, 3 Mermaid's Purse - Weird Shark or Ray Eggs has ended.
The auction is for 3 mermaid's purses. There is a lot of folklore surrounding these. Great for shark, ray, or skate fans, those who collect natural items, or those working with the energy of the sea.
On the science side, these are the egg cases for certain sharks, stingray, and skates. A live shark emberyo lives inside, eventually breaking though and then these cases wash up on the shores empty while the shark begins its life in the ocean. They were collected on the coast of Virginia in January of 2012.
As for folklore, these have been called mermaid's purse, and who knows what would wash up inside, or if its owner is dwelling just offshore, waiting for you to swim out and meet her. Mermaids are present in cultures all over the world. Here are a few of the legends:
Ben-varry: (Isle of Man) Ahe generally appears as a benevolent fish-tailed woman, though some few have been known to lure sailors to their doom.
Dinny-mara: (Manx) not normally seen or described.
Havfrue: (Scandanavian) Beautiful in appearance, long golden hair and carries a golden comb. Her appearance is an omen of poor fishing and storms. The havmand, the merman, is considered handsome with green or black hair. He is generally helpful to humans.
Merrow: (Ireland) The females are beautiful. Males are green with red eyes and pig ears. All have long fish tails and webbed fingers. They are normally friendly to humans, even intermarrying.
Merrymaid: (Cornish) Their actions depend solely on their whim at that moment. While some merrymaids rescue sailors from drowning, others encourage sailors to drown. Their siren song as they sit on nearby rocks causes ships to founder and sink.
Melusine: twin-tailed mermaid, depicted in medieval bestiaries.
Ningyo: Japanese monster. Depicted as human-headed fish. The fish-flesh grants the gift of immortality when eaten, and their blood can be used to cure all ills. Their tears form of pearls which are highly prized in magic.
