It's interesting to consider how persistent is the idea of human/animal combinations. I am tempted to cite the "current" fad of vampires except that it is not really current so much as ongoing. In film, one only needs to look at Nosferatu (1922) and the dozens (if not hundreds) of vampire films that followed. Right now we have the Twilight series which features both vampires and werewolves. Humans may assume other animal forms in other cultures. In West Africa the leopard is often the chosen form of black magic or juju priests. The combination is not always dark and horrible - here on the Inner Harbour Causeway we have a charming mermaid. This is Hilarie Ann Higgins who performs with her accordian as the Mesmerizing Mermaid.
