Native to all continents but Antarctica, there are more species of rodents than any other mammal order. Rats and mice that have adapted to living with humans make rodents even more familiar.
If there’s no further information below, you might want to check out Rodentia’s children. Otherwise, you can try Google or check back again in a few weeks; GeoZoo is under constant development.

Distribution
These are not precise range maps. This series of maps merely indicate the continent(s) and ecozone(s) various groups of animals are native to.Rodents are one of the most widespread mammal orders, native to all continents but Antarctica. Yes, there are even tiny rodents native to Australia.
The northernmost rodents are the hardy lemmings that call the northern tundra home. However, rodents are far more diverse in the tropics. In fact, South America boasts more rodent species than any other continent, even though it’s one of the smallest continents.
Some rodents get a free ride, following humans around the world. The Big Three are the house mouse, black rat and brown rat, all of which are native to Eurasia but have probably become the most widely distributed mammal species after humans.
Habitat Niche
Diet
Their formidable incisors are a clue that rodents are primarily herbivores. However, there are exceptions, including some omnivorous rats and the carnivorous grasshopper mouse, which preys on other mice.
