1. What is the major ungulate groups?Artiodactyla (even-toed) and Perissodactyla (odd-toed), with distinct weight-bearing digit arrangements
2. What is the ecological impact?Facilitates predator evasion, long-distance migration, foraging efficiency, and influences vegetation structure
3. What is a hoof and why is it special?A hoof is a hard, keratin shell that covers the last bone of an animal's toe. It is made of beta‑keratin, which is very tough and protects the foot from wear and tear.
4. Why do some animals have wide hooves and others narrow hooves?Wide hooves, like those of reindeer, help animals walk on soft or snowy ground. Narrow hooves, like those of horses, give a better grip and speed for running.

Ungula: The technical term for a hoof, referring to the keratinous covering of the digit in ungulate mammals.
Distal Phalanx: The terminal bone of a digit, encased within the hoof capsule, which bears the primary load.
Laminae: Interlocking folds of epidermal and dermal tissue that anchor the hoof wall to the underlying bone.
Cursorial Adaptation: Physical traits that enhance running ability, often seen in odd-toed ungulates like horses.
