Mole nose. Coloured scanning electron micrograph (SEM) of the snout (pink) of a mole, showing specialised bulbous papillae (projections) known as Eimer's organs. Eimer's organs are present in most moles and are made up of epidermal (upper skin layer) cells that are infiltrated by many nerve fibres. These fibres end as a swelling just before the very outer layer of the epidermis, making the snout extremely sensitive to touch. Most moles are virtually blind, so they rely on their specialised ability to sense movement in order to survive.
