The pudús are two subspecies of South American deer, and are the world’s smallest deer. The name comes from the language of the indigenous Mapuche people of southern Chile. There is the northern pudú from Colombia, Ecuador, and Peru, and the southern pudú from southern Chile and southwestern Argentina.
Pudús range in size from 32 to 44 centimeters tall, and up to 85 centimeters long. As of 2009, both species are classified as endangered.
