A hoof is a sturdy and specialized structure found on the feet of certain animals, such as horses. It consists of a tough outer covering made of keratin, similar to a human fingernail, which protects the underlying structures. The hoof provides support, traction, and shock absorption while the animal walks, runs, or jumps. It is an essential adaptation for these animals' locomotion and plays a crucial role in their overall health and well-being. 🐴👣
