Deer are mammals that belong to the Cervidae family, characterized by their hard hooves and antlers that are exclusive to males. Typically found in North America, Europe, Asia, and South America, they are herbivores that graze on leaves, bark, and fruits. Throughout the year, deer go through several stages that relate to their growth and feeding habits. They possess an exceptional digestive system that allows them to regurgitate and rechew their food, which helps in the proper digestion of plant fibers. They are also known for their agility and speed, enabling them to escape from predators easily. Due to their graceful and impressive appearance, deer have become widespread in the cultural fabric of many societies, especially in myths and folklore.
