Final answer:
Deer are characterized by their four limbs for movement, distinctive cylindrical faces, and antlers mainly on males. They have traits common to mammals such as fur covered skin, endothermic bodies, and external ears.
Step-by-step explanation:
Characteristics of Deer
Deer have several distinguishing characteristics that make them unique animals in the animal kingdom. They possess four limbs utilized for locomotion, allowing them to be specialized for running, as observed in their long legs and hard hooves adapted for swift movement. Deers are recognized for their antlers, which are generally found only in males. These antlers can vary in size but serve important roles in mating displays and combat with other male deer for territory or mates. Additionally, deer have external ears that enable them to detect sounds crucial for their survival in the wild.
Other characteristic features of deer include their ability to move their eyelids and tail, which can be of various lengths depending on the species. Unlike some misconceptions, deer cannot shed their tails. Their diet typically consists of vegetation rather than insects. The unique facial structures of deer, such as cylindrical faces, set them apart aesthetically from other ungulates, like horses and bulls.
Deer are part of the class Mammalia, meaning they possess a bony endoskeleton, breathe with lungs, and are covered with hair or fur. Their mammalian traits also include having mammary glands and being endothermic (capable of regulating their body temperature).
