Deer, much like humans are mammals. Mammals of course are known to have their young seat on the mother's milk from the mother's nipple. Much like other mammals deer are also warm-blooded. Being warm-blooded means that the deer's body temperature maintains a fairly consistent temperature despite the surrounding environments temperature. The deer's body hair helps to keep the deer warm in colder environments.
There are caribou can be found in the far north which have a thick coating of body hair. A majority of other dears conquer the world will tend to have short, shiny body hair that lays flat giving the deer’s hair a smooth silky like appearance. Those deer that can be found in tropical climate regions tend to have a thinner coat of hair.
Legs and hoofs: Deers all have long and thin legs which allow them to be quick and able runners. Deer will move their legs so quickly with longer strides. It dear doesn't have a typical five toed foot but on the other hand have to center toes that constitute their feet. Each of the deer’s two toes are protected by a hard sheath which is named a hoof.
A deer will often pounce forward in motion using their tiptoes. They have two additional toes named dewclaws, which develop higher on the deer’s leg, which are largely useless. When tracking through snow, the deer’s dewclaws leave dot like formations on the snow. Deer have immense speed which they employ to escape being prey for much larger or smaller fierce predators. A white tail deer can reach the fast speed of 40 miles per hour, and can pounce up to 6.1 meters towards their desired location. The moose, also a deer, can run roughly 31 kilometers per hour.
Head: Deers tend to have slim narrow heads, with small noses, and the mouth of common cattle. The lips can fluctuate easily, as the deer employs their lips to get hold of food. Majority of deer have lower teeth only, often at the front of their mouth. There is a thicker patch of rougher skin situated in the upper part of the deer’s mouth which they use as upper teeth.
They use the lower teeth, and upper rough skin to pull apart leaves for digestion. The deer has large eyes at the side of their faces; but it is important to remember that the deer does not use their eyes as dependently as they do their ears and nose; which both act as their alarm system for incoming predators.
Antlers: Antlers are just growths (outward) of bone, which are intact with the deer’s skull. These are hard, bone like devises that these deer’s uses as weapons, to ward of predators. Male deer will use these antlers to fight off other deer’s trying to mate with the deer’s desired mating partner.
Other male deer will use their antlers to fight for the leadership role of the herd of which they are member. Those deer that are found in colder climates, tend to lose their antlers every winter and thus grow new antlers in the ensuing spring. Newer antlers are often incredible soft, and grow expediently.
