Rodents | Rodentia Drawings & Dimensions

Rodents are classified by a single pair of continuously growing incisors in both their upper and lower jaws; the length of their incisors are maintained by gnawing, which is how they eat. The diet of Rodents usually consists of seeds and plants, but some species do have more varied diets.
