Why are the feet of the vicuña structurally distinct from those of horses or deer?
Answer
They have padded soles and modified nails instead of hard hooves
The vicuña's feet are equipped with tough, leathery, padded soles and blunt, modified nails rather than hard hooves. This design provides excellent traction and cushioning on rocky, uneven terrain while minimizing ground erosion, making it far better suited to the fragile high-altitude landscape than the hard, damaging hooves of other grazers.
