Credit for picture The yale or centicore, is a hybrid creature from European legend. Descriptions vary slightly. The yale is black or tawny. It is the size of a goat with the tail of an elephant and a boar's jaw. Some medieval bestiaries said it had spots, the head of a goat, and the feet of a unicorn. It has two long, straight horns which can point either forward or backward. Due to its horns, the yale was a creature of heraldry and meant proud defense. Credit for picture
