Are kangaroo rats only found in New Zealand and Australia?
No. Some species of wallabies, which are smaller members of the kangaroo family, have been introduced to New Zealand.
Kangaroos are native to Australia alone - no other continent or island. Tree kangaroos can be found in New Guinea as well as in the far northern rainforests of Australia, but that is the only variety found anywhere else apart from Australia.
How did the desert kangaroo rat get its name?
it's a rat that lives in the desert and jumps, it's kinda self explanitory
