The term "pedetidae" refers to a specific family of mammals that includes various species of jumping rodents, such as the springhare. There aren't many commonly used synonyms for this particular term, as it is a scientific classification that is not often encountered in everyday conversation. However, some alternative ways to refer to these types of animals include using the more general terms "rodent," "hare," or "jumping mammal." It's important to bear in mind that not all rodents or hares are part of the pedetidae family, so it's best to use more specific language when talking about these creatures in a scientific context.
