What type of teeth do lagomorphs, such as cottontail rabbits, possess?

1. Flat molars

2. Canine teeth

3. Pear shaped teeth

4. Continuously growing incisors

The correct answer is: Continuously growing incisors

Lagomorphs, such as cottontail rabbits, are characterized by having continuously growing incisors. This is a defining feature of their dental anatomy, which allows them to effectively gnaw and process tough vegetation in their natural habitat. The incisors are specialized for cutting and are shaped to be effective in this role, making them well-suited for the herbivorous diet of these animals. In addition to the continuously growing incisors, lagomorphs also have molars that are adapted for grinding plant material, but the key distinguishing feature lies in their incisors' growth pattern. Unlike some other mammals, the incisors of lagomorphs do not wear down to a certain length but instead grow throughout the animal's life. This adaptation is crucial, as it compensates for the wear and tear that occurs from their constant feeding on fibrous plant material. The other options do not accurately reflect the dental structure of lagomorphs when it comes to their most notable characteristics. Understanding the unique dental adaptations of lagomorphs is important for wildlife rehabilitators, as it informs their dietary requirements and husbandry needs in rehabilitation settings.
