Resembling nothing so much as Chewbacca's children, two of the world's tiniest monkeys debuted recently at the Frösö Zoo in Ostersund, Sweden.
Shown here shortly after their birth, these pygmy marmosets are exceedingly rare. It's not because they're twins though—pygmy marmosets are typically born in pairs—but because they're albinos, deficient in pigment.
One of the twins didn't live for very long. The supposition is that it had a deficient immune system somehow linked to its albinism.
