Deer: Key Facts

Deer are a fascinating species that are fun to spot, especially with their elusive nature. Many people don’t realize how many different types of deer exist in the wild, and how much they vary.

Deer are ruminant mammals. Ruminant means that they are hoofed, herbivorous, and are grazing mammals that have special 4-chambered stomachs. Cattle, sheep, buffalo, goats, giraffes, and camels are also ruminant.

There are over 40 different species of deer, many of which have several different subspecies. However, you’ll most likely only encounter a handful of them in your lifetime.

Here’s a table that can help to identify and differentiate the most common types of deer.
