@unityofknowinganddoing: Deer (鹿/lù) are a group of hoofed, ruminant mammals found on every continent except Antarctica. Their most distinctive feature is the presence of bony antlers on the males; these antlers go through an annual cycle of shedding and regrowth. Deer vary significantly in size, ranging from the massive moose to the tiny pudu—the latter being about the size of a dog.
