kangaroo
Refers to the Australian marsupial. Common in everyday contexts.
I saw a kangaroo in Australia.
ワラビー and カンガルー are both marsupials that hop on their hind legs, but カンガルー refers to the much larger kangaroo, while ワラビー is used for the smaller, similar-looking species.
Borrowed from English 'kangaroo', ultimately from Guugu Yimithirr gangurru.
