What dental feature does the Vicuna possess that aids in close grazing?
Answer
Continuously growing lower incisors
The Vicuna exhibits a highly specialized dental adaptation that is rare among ungulates. Its lower incisor teeth grow continuously throughout its life. This trait is essential for survival in high-altitude environments, where it must graze extremely close to the ground to reach sparse, low-growing vegetation. By constantly regenerating this tooth structure, the animal prevents the excessive wear that would otherwise occur from abrasive ground contact, allowing it to maintain its diet and overall health in a demanding ecological niche.
