Ear length
The ear length is a body measurement and describes the length of the auricle of mammals from the lowest point of the auricle, the indentation in the cartilage , to the outermost tip of the ear. The standard measure is taken with a pair of dividers or a transparent ruler . Overhanging hair is not measured.
Sufficiently accurate measurement results cannot usually be obtained on living animals. Measurement on freshly dead animals is recommended; measurements during rigor mortis , however, are not recommended. The preservation usually affects the length and shape of the auricles. The auricles of bellows and skins shrink quite a bit.
