What is the difference between a gopher and chipmunk?

"Gopher" is an umbrella term that applies to various kinds of burrowing rodents, due to their similarities and scientific classification. They include pocket gophers, ground squirrels, chipmunks and a variety of prairie dogs. All are commonly referred to as gophers. Chipmunks have distinctive black and white stripes that run down the back of their brown bodies. Pocket gophers are brown with no stripes. Ground squirrels are light beige in color. Prairie dogs are much bigger than any of these rodents and come in many varieties.
