Vicuña
The main colour of the soft, wooly coat (hair) is ochre, light cinnamon, or reddish brown. The lower part of the body, the inside of the legs, and the underside of the head are white. On the chest, at the base of the neck, there is a 'mane' of white hairs. They can be 20-30 cm (8-12 inches) in length. The vicuña is very slender (slim). It has long neck and skinny limbs.  The head is small and wedge shaped. The ears are small and triangular. The incisors (front teeth) of the vicuña are always growing. It is the only even toed-ungulate with teeth that always grow. The enamel is on only one side. This is because of the tough grasses which they eat.
