What is a "sand rat"?

The fat sand rat has large, round ears, a stocky body, and long hind legs adapted for hopping, similar to a kangaroo rat. It is known for its ability to survive in harsh desert conditions, obtaining water from its food and conserving moisture through various physiological and behavioral adaptations. However, it's important to note that the term "sand rat" may be considered offensive or derogatory when used to refer to people of Middle Eastern or North African descent, and should be used with caution and sensitivity.
