Several years ago, Equus did an article about the positioning/number/etc. of hair whorls on the heads of horses and their potential relationship to temperament, behavior, and intelligence. It sparked an angry response from many readers stating that Equus shouldn't be printing such "nonsense" because they are usually a highly respected magazine that only prints "the facts."
Personally, I thought the article was very interesting!
There is an article in this months issue of Horse & Rider on the same thing.
That is really interesting ... I don't think I've ever seen that before. Jubilee has a whorl between her eyes like most horses. As for a meaning behind it, someone told me that if a whorl is centred evenly on a horse's face it means they are intelligent. But then again, that could just be an old wives' tale. :P
