What unique feature characterizes the lower incisors of the vicuña?
Answer
They are continuously growing throughout life
Unlike other camelids, the vicuña possesses lower incisor teeth that grow continuously throughout its lifespan. This trait, similar to that of rodents, allows the animal to maintain a functional dental surface despite the heavy wear resulting from its habit of closely cropping tough, abrasive grasses near the ground.
