A Jenny Haniver is a preserved ray or skate that has been cut, folded, and dried so it resembles a miniature dragon, devil, or other fantastical creature. Though they can look like odd pieces of folklore, they are made from real sea animals and shaped by hand to create a dramatic illusion.

These objects date back to at least the sixteenth century, when they circulated as curiosities among sailors and collectors. Their appeal came from the mix of natural history and showmanship: ordinary marine animals were transformed into something that seemed rare, exotic, or even supernatural.

The name Jenny Haniver has a murky background, but one theory links it to the phrase jeune d'Anvers, or "youth of Antwerp." That possible origin fits the long history of trade, ports, and traveling curiosities that helped spread such objects from place to place.

Today, Jenny Hanivers remain a striking example of how craft and imagination can reshape natural materials into myth-like forms. They sit at the crossroads of seafaring history, collecting culture, and the enduring fascination with creatures that look half real and half legendary.
