Short description: Eponychium in newborn hoofed animals

In hoofed animals, the deciduous hoof capsule (Capsula ungulae decidua) is the eponychium in fetuses and newborn foals.[1] It is a deciduous structure, which disappears as the animal grows. In equines, they are shed soon after a foal begins to stand.[2] The shedding process can vary from dropping-off whole to the gradual wearing down of the capsule.[2] Common names used in lay literature include "golden slippers", "fairy fingers", and "horse feathers".[2]
