There are currently over 100 different subspecies of deer roaming the Earth, according to Deer Worlds. Surprisingly, they can be found throughout all continents with the exception of Antarctica, which is too cold.
According to the habitat tracker website, deer are able to live in many different habitats. However, they do not inhabit areas such as Alaska, Hawaii or desert regions, but they are frequently seen in grasslands, forests, plains, mountains and prairies.
In a comfortable climate, deer are able to thrive with good access to water and food. They tend to eat plants such as vines, grasses, shrubs and leaves. Areas with these food sources also provide deer with cover from predators.
