Various species of Deer

Deer are a diverse group of hoofed mammals found worldwide, ranging from the small pudu to the large elk. Common species include white-tailed deer with a distinctive tail, red deer native to Europe, and moose, the largest members with broad antlers. Reindeer or caribou are adapted to cold environments and migrate seasonally. Other species like axis deer and sika deer are native to Asia. Deer vary in size, habitat, and antler structure, but all play vital roles in ecosystems as herbivores and prey, with some species valued for their meat and cultural significance.
