They're Japan's odd couple.
Capybaras and squirrel monkeys, unlikely neighbors in the wild, are living in the same enclosure at a zoo outside Tokyo and so far, they're loving it.
The monkeys ride on the capybara's backs and kiss the world's largest rodents, who tolerate their tricks. But in the wild, their paths do not cross -- capybara's live on river banks while the monkeys live in forests.
Keepers at the Tobu zoo said it took the capybaras years to tolerate the monkeys.
What next? Cats with dogs?
