With its cartoon-like skeleton and blood-red muscles on display, the horse parading around the race track has all the appearances of a very late Halloween prank.
Resembling an equine beast turned inside-out, the otherworldly creature daubed in brightly-colored paint completes a mini obstacle course, drawing excited murmurings from the gathered crowd.
It's not a ghoulish apparition, but a living piece of art, used to vividly show the inner workings of our four-legged friends.
Equine massage therapist Gillian Higgins spent two years painting all 11 anatomical systems on horses -- from the skeletal, to the digestive, muscular, respiratory and reproductive -- as part of an innovative teaching aid.
The animals, decorated in washable, hypoallergenic paint, are then displayed at races and equine training events across Britain.
"Anatomy can be quite dry and difficult to remember," said Higgins, manager of equine educational organization Horses Inside Out, based in Nottingham, England.
"But if you see a horse moving and jumping around with a skeleton painted on the side, it really brings it to life.
"It's not just about knowing the names of the bones, it's about understanding exactly what they do."
Higgins first started painting horses six years ago, to help equine massage students memorize the animal's 700 muscles.
Today, her carefully decorated horses appear at veterinary classes, industry lectures and racing competitions.
