The term 'forest ruminant' refers to a type of mammal that lives in forests and has a four-chambered stomach. Two examples of forest ruminants are the OKAPI, which is a five-letter word, and DEER, which is a four-letter word. Another example is the red DEER, which is a seven-letter word. All three of these animals are herbivores and have a diet consisting mainly of leaves, grasses, and other vegetation. They also have hooves and antlers, which they use for protection and to mark their territory.
