Antlered deer are a type of deer that have antlers, which are bony structures that protrude from the head and are shed and regrown each year. The three most common antlered deer are elk, HART, and STAG. Elk are the largest species of deer in North America and can weigh up to 700 pounds. HART is another name for red deer, which are native to Europe, Asia, and North Africa. STAG is another name for male red deer, which are distinguished by their large antlers.
