The moose or elk is the world's tallest, largest and heaviest extant species of deer and the only species in the genus Alces. It is also the tallest, and the second-largest, land animal in North America, falling short only of the American bison in body mass. Most adult male moose have broad, palmate antlers; other members of the deer family have pointed antlers with a dendritic ("twig-like") configuration. Moose inhabit the circumpolar boreal forests or temperate broadleaf and mixed forests of the Northern Hemisphere, thriving in cooler, temperate areas as well as subarctic climates.

Growing antlers are covered with a soft, furry covering called "velvet". Blood vessels in the velvet transport nutrients to support antler growth.
A deer or true deer is a hoofed ruminant ungulate of the family Cervidae. It is divided into subfamilies Cervinae and Capreolinae. Male deer of almost all species, as well as female reindeer, grow and shed new antlers each year. These antlers are bony extensions of the skull and are often used for combat between males.
