This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Pandi (Medieval Bestiary)
The Pandi (or Pandae) in Medieval bestiaries and Greco-Roman geographic works were a race of giant-eared people with eight fingers and toes and white hair that turned black with age. In his Indica, the historian Ctesias located them in the mountains of India; he describes them as a warlike race of bowmen and spearmen and claims that they are born with a full set of teeth.
Pliny the Elder, in his Natural History, adds that they live for two hundred years. Both male and female children have white hair, on the head and eyebrows. Up to the age of thirty the men have white hair all over the body; it then begins to turn black, and at the age of sixty it is quite black.
