The largest species of deer is the moose, known for its impressive size and distinctive features. Native to North America and parts of Europe and Asia, moose can weigh between 800 to 1,600 pounds and stand about 5 to 6.5 feet tall at the shoulder. They are characterized by their long legs, large bodies, and the broad, palmate antlers found in males. Moose are primarily herbivores, feeding on leaves, bark, and aquatic plants. Their unique adaptations allow them to thrive in northern habitats, where they play a significant role in their ecosystem by influencing vegetation growth.
